OK, I really didn't want to say anything beforehand since it's not ready, but since you guys brought it up, you can check this out:

I've been toying with it since last year for exactly the reasons you guys have mentioned in this thread. I've gotten pretty tired of the guidelines and restrictions of Wikipedia, so I've pretty much stopped updating the Underworld content there. I like Wikipedia very much, but it's just not the appropriate repository for the kind of trivia and information stuff that we like for Underworld.
MediaWiki, the most popular Wiki software (the same software that runs Wikipedia), is fairly configurable for access. I can set it (as I have now), so that articles can only be edited by registered users. User registration can be handled in numerous ways, but I think I would leave it as I currently have it set, where accounts have to be manually created by administrators. Spambots are a big problem with Wikis, and unless you're running Anti-spambots, their crap has to be cleaned out manually.
I had initially thought to restrict accounts to a select few whom I trusted to have a fastidious attention to detail. People like -1 and Jan immediately came to mind. I wanted the information to be super-accurate, super-consistent, and super-complete. I wanted complete, little details, like all the exact track timings and where tracks are available, and all the catalog number, and so on. However, now I do see the need for less detail-oriented information too, like Underworld Socks, and other anecdotal contributions. I'll have to look into it, but I think I can set up different classes of articles, so that only users in certain groups can edit certain articles.
So, as a lot of you know, I'm anal about trying to get everything "just right" the first time, which means things take a long time to happen sometimes. A lot of other projects and things in my life have been taking priority over this project. However, at least the following things need to happen before I feel comfortable "officially launching" the site:
1. I think I've got most of the basic framework laid for song articles. I still need templates for singles and album/EP articles.
2. I need to update MediaWiki. It's running a rather old version that's deprecated, but I need to upgrade PHP on that server before I can update MediaWiki. I'm working on it.
3. I do want the Wiki design to be consistent. There are probably a lot of templates, frameworks, and structures that will need to be set up to support the articles. If anyone has Wiki experience in setting up those kinds of support structures, I'd definitely be interested in hearing from you.
4. I haven't registered a domain yet either. I was thinking underworldwiki.com. Any thoughts or other ideas?
Edit: And live shows; I haven't even considered how to incorporate those into the Wiki. A lot of that content and effort would be duplicative of
http://uwlive.rowla.com. I don't even think a Wiki is the best method for storing and presenting all that data. I think a custom database and interface like what Mike's been trying to build would be much better suited to that task.
