hey, i just upgraded our wiki software. some stuff is a little screwy, like uploading images. also, external images seem to be odd, i'll work on those. you'll likely see some error message on top of the page when you upload an image, something about permissions being wrong, but it still seems to work. i don't know why, i'm still investigating and hope to find out soon.
the reason for the upgrade was a serious security hole in the older version of mediawiki, as well as some newer features such as the ability to archive and restore already deleted files and pages. i'm still working on setting that up, but that may come in handy once this is opened up to the public.
anything else that is weird, lemme know please. i think it's all working correctly. i had to upgrade some portions of PHP to PHP5, which has some advantages, but caused a few weird errors on the backend.
