Wiki added!
After some configuration hassles, I’ve added the Wiki!.
I even threw a FAQ up and added the link to the sidebar.
The configuration hassles were minimal, mostly involved re-reading the directions five times to enable mysql support with encrypted password. Then I had to change a setting in the php.ini file. The error code was a little misleading that it made me think it was a Wiki configuration problem, instead of PHP, but some googling around got me the answer.
The funny thing about it is the Wiki comes with a number of differently themes to choose from (I have MacOSX up now). The built-in WordPress theme for Wiki was the exact same WordPress theme I was using on the blog. Until yesterday that is when I changed. But it’s staying the way it is.
