Instead of making new versions of pages because you've seen alternate spellings, it's a lot easier and more convenient to simply make a note of the different spelling on the existing page. Otherwise what'll happen is both pages will appear in the search box, and anyone clicking on the less complete one might assume we don't have any further information on the subject. For example, we already have a Kokuboro page, which is the more common English spelling we use here.
That's strange, I was worried about alt spellings so I searched 'kokubo' but didn't get anything... guess it has to be exact.
Part of my worry is if I don't document stuff as I watch it, I'll have forgotten about all but the most major stuff by the time I'm finished... but this wiki is so extensive I'm thinking I should ignore that habit and assume all the details are here :D I guess it's surprising that it's so well done, usually only expect to see that in popularity behemoths like Ble/Nar/One.
It'd be nice to get into the mode of just pure enjoying something on the first runthrough, like how it used to be.
From what I've seen so far, you're watching the subbed anime version. The only issue there is that's kinda... unofficial. In other words, first there's the manga that the author herself writes, then there's the Japanese anime adapted from that, then fansubbers produce a subbed version of the anime (I tend to think of it as a rough draft), then official subbers produce a more polished (and edited) version of the anime. So through all those versions, certain details and names are going to change, possibly more than once. To me what's most important is the content: so long as you get that basically right, the names aren't as important. And anyone that's a fan of anime or manga knows the names can change without warning. No danger of that here since the series is finished, thankfully.
I suggest enjoying your first time through the anime. I think we have the anime pretty well covered as far as episode summaries go. Almost everyone who ever was a regular contributor here at least saw the whole anime. So if we're missing any anime details, it's not because we don't know about it, but because we just never got around to it. It's very unlikely that we need any new pages as far as anime characters are concerned. But I know we can use some more pictures/screencaps here and there.
The anime and manga summaries are basically done except for some name-altering here and there. Where we always ran into trouble was that we didn't have enough people who had read the manga (Kekkaishi was never as popular as Bleach or Naruto, I guess). Manga readers are really the only ones that can fill in the character plots beyond what the anime covers. I practically wrote all of the manga summaries myself with one other person adding title info and pictures. Now it's a matter of going back and adding all the relevant information to individual characters' pages. Which takes a while since I'm the only one doing it.
Also, in the interest of helping people find things, I've been wanting to get categories better organized, which you have a good start on already. But we may actually need a page devoted solely to getting people to where they want to go. Which reminds me: do you not have the drop-down menus at the top of the page that you can mouse over? At least as far as main characters and some concepts, that should show you how we've been spelling them.
If I recall correctly, I got the idea from the Fairy Tail and Bleach wikis. I am still working on a page that will direct people to things they want to find. For example, I think it might help if that page linked directly to some of the category lists, so that specific characters and Ayakashi are easier to find.
A couple of things I should mention. Pictures are fine, but we generally only use one per section (for example, only one is really needed under Appearance). Also, we try to avoid screencaps with untranslated Japanese, unless there's a specific point to doing so. And you don't need to actually write what episode someone first appeared in under Appearance, there's already a space for that built into the character template boxes, and most, if not all of them, should be done already.
For Toshimori's two friends (and really any issue where the manga and anime don't match up), we assume the manga is right, if only because the manga is the original and the anime is the adaptation. If I recall correctly, the names we have currently are based on translations of the manga as opposed to the anime. We've been down this road before and the anime has come up short on certain issues, though we do try to include both versions even if they differ greatly. At any rate, most plot summaries here (unless they're specifically episode summaries) should be primarily based on the manga.
Yeah I noticed some interesting ghost characters here who don't even show up in the anime, makes me want to pick up reading the manga. I switched over assuming the anime might cover it all, and I'll finish it first, but obv. a bad assumption to make about any manga>anime relations nowadays.
There's a lot of content you miss if you only see the anime. But most of it does come after the Kokuboro arc, which the anime covers pretty thoroughly. So you would mostly be fine if you saw the anime, then picked up reading the manga at Chapter 122. You might miss a few minor characters, but then they are minor.
