Sorry, I meant to reply earlier.
I think this is a good idea, although I'm not 100% sure how you would like to implement it. For example, do you want a sheet like the Fansub Wiki, or should visitors click to series specific pages for further information? Stuffing to much info into one sheet probably is not a good idea.
How about something like the
Season Preview posts seen on Random Curiosity? The advantage of doing such "posts" ourselves would be that we don't need to rely on one person to create such overviews, plus we can add the AnimeSuki connection you mentioned. The descriptions would need to contain less bias of course.
Btw, It would be no problem hosting this. I can have MediaWiki (or any other Wiki software) installed in no-time. Customizing that software however, may be a bit more tricky as far as the forum tie-ins are concerned (logins etc).
Should this new wiki be on it's own domain (which I'd be willing to fund) or something like
wiki.animesuki.com?
