state of the wiki
I would like to see something on the main page that shows that the community is active. Maybe some parts of the recent changes, current discussions, lately visited pages or last updated robots. Because when i started with robocode and came to the robowiki (trough the robocode page) it looked to me very abandoned because i was not familiar with the "recent pages" or "talk pages". I had a lot of questions and had no place where i could ask. I think i hit the first talk page by accident 3 month later and it took me even longer to find the "recent pages" (i know its a shame because it is linked on the main page). But i guess if you are not used to how wiki works behind you didn't notice it is there.
Some informations are hidden quite well if you don't know what you are looking for. Lets say the code size related pages. The informations about code size are spread over 3-5 pages i guess and you really have to know what you are searching for.
After i got used to the wiki i found out that most of the interesting informations are on the talk pages. Maybe it is possible to integrate the discussion threads, if they relate to the content, as links in the wiki page as well (probably -1 for bad style but it would save the time to edit the page after each new discussion).
For editing/making pages i would second Tkiesel and feel outclassed and overshadowed by the robocode veterans, plus i don't think my spelling is appropriate for that. I'm also very afraid of moving/summarize pages or insert relevant links because i can not estimate the damage it would bring.
Lately i was in the moot to make a bot pages for the probably most influencing bots to the robocode community - the sample bots :). Just because i think they deserve it and probably most of the robocoders have struggled against these little buggers. I don't know but i guess it would be nice if the new robocoder can start from these bot pages to discover the wiki basics. For example links to linear targeting on Walls or circular targeting an SpinBot, radar lock on SittingDuck or orbiting movement to show how to circle around SittingDuck and so on. My guess is, it would be some sort of entertaining tutorial, and also leads to the feeling what you need to make a robot. I don't know , maybe i'm wrong on that.
All in all i can say, now that i'm a little more used to the wiki i'm very happy with it and like the way how it bonds the community. I'm keen to help with whatever you need.
