state of the wiki
If you want to make new pages, or edit anything, please just do it. If you want to change the main page to show more prominent links to Recent Changes or some sort of howto for the wiki, go ahead. If we don't like it we'll say. After all, it is easier to get forgiveness than to get permission =) Myself, I hardly ever look at the main page, I just bookmark Recent Changes.
When I first came to robowiki (2005/6 or so, I think), I also didn't see the recent changes page for about a week and was impressed that everybody managed to find my page. Of course, that was on the old wiki, but I think a lot of the same problems are still around.
I agree, what the wiki needs is something to get beginners acquainted with the layout (the talk pages, recent changes) and maybe a glossary of commonly used terms and 1 line explanations of them (VCS, wavesurfing, DC/KNN, flattener, HOT etc) with a link to their page. I'm busy over the next few weeks (off to Mexico for Robocup 2012!!), but feel free to do whatever you feel will make the wiki better. The wiki is a community resource, and as part of the community you are strongly encouraged to do whatever you think will help the most! If you want to update old bot pages, or migrate anything over from the old wiki, just go ahead.
