We're a bit off the original topic, but out of curiosity why would a wiki be locked/only a mod can edit? I know that was the case several months ago when they were first being tested, but once testing was over/they went live I don't see a reason to have a wiki locked. That seems to defeat the purpose of a wiki. On a dif note - learned something today. Never noticed the + or - before on the wikis.
Cheers.
