Incorrect terminology on the blog and wiki stuff. CSS is what makes this site more than just plain text on a white background. Or in my case, black... you get the idea.
They want to add a wiki to the site, which I think is as simple as getting the wiki software files (like the forum files) and copying them to the site root.. Then add links to the rest of the site of course. Well, and then you have to add all the data. Same with a blog, but it would be 50 times easier to just run that offsite and link to it. Do NOT ask me to run or assist a wordpress on this site because I hate that crap software.
