Leeor,
I think the wiki theme matches the rest of the website very well. It is good to see the links back to the rest of the site at the top of the wiki as well.
Two things to consider on the wiki.
1. I have trouble seeing which text represents hyperlinks until I hover over them with my mouse. I think offsetting the color or weight or adding an underline to links that are not being hovered over would make it a lot easier to tell. See attached picture for I mean. All of the text in this list represents hyperlinks, but I can only tell on the bottom one my mouse is hovering over.
2. The wiki font is a little small. Maybe I'm finally getting old or something.
If we bump the default font up a pt or two, I think it would be easier on the eyes and fill the pages out a little better.
Thanks for putting all the time into unifying the themes of the sites.
EDIT: I feel like the default font for messages in the forum could be raised a pt or two as well. Maybe some other people could weigh in. If most others like the text this small I'll just suck it up.
