Edit rights to that whole wiki are by invitation-only, and we assume that anyone thus invited will practice restraint (or, failing that, not want to see Hybrids when they dream) Once or twice someone's fixed a typo in the release date of a patch or whatever. In general please just tell us the error and we'll fix it ourselves, because it's possible the error was cleverly correct
I've fixed several, generally
long after a patch has been released. Did about five a week ago.
While such fixes are likely to go unnoticed, they make me feel good (as I tend to read the updates once every few months and have several to catch up on, so I'm probably not the only one).
Think I've fixed one
math related error once, but it would have been a long time ago.
(Oh, and just so everyone's clear, I was invited after having started over a dozen threads and mantis entries related to very minor wiki typos; the "teh" and "n" kind. And it's about all I use my edit powers for.)
