I used mouseovers for a few days, but enough people complained that I took them away.

Some people didn't like not being able to highlight the text. Other people said they were used to just clicking anywhere on the page, for example if another window was opened on top of the forums they would click the forums window to switch into it, and of course with the mouseover you can't just click anywhere anymore.

So for a while I changed the mouseover to not make the entire cell a link, to just do the color change, but I didn't like that, because if I see a color change I expect it to be a link. So now I'm back to regular cells with no mouseovers.
