Well ... although I have never been a person that wrote stuff on wiki's, I have been a forum moderator at several community websites for years, so my writing skills should not be a problem.
Thing is I wouldn't know where to begin. If you would ask me to do a specific thing that would help you get info on the wiki faster then I could do that, but you'll have to push me in the right direction.
Like if you could get me a quick document with for instance Results.RegEx and it's arguments, I could write it up so that it's readable for the public and make some examples with it. (so that you can just give the quick and basic technical info and I'll put it on the wiki in a readable way)
I'm just thinking out loud, I have no idea where to begin or what todo. All I know is I'm willing to help you, if I can as I find this a very interesting project.
