Software updates enhanced security and permissions in WordPress and wiki platforms, suggesting better functionality.
I've updated the wordpress install to 2.0 which has a lot more features and seems to be better setup for permissions and what not. I also upgraded the wiki to 1.5.5 to deal with some potential security holes with WMF files. I also changed the permalink structure so that the links are informative by date and post-slug. I like this much more.
