What would be required of a moderator? As far as I have seen, this site is only visited by mature, sensible people. I don't think that I have seen any thread that really needed a moderator's touch. Now, don't think that I'm sucking up, I'm just comparing to other forums.
If you just need a name for a moderator, I can volounteer. I can't guarantee that I will check posts every day, but since the post rate of this forum isn't very high and the good nature of the members, I think that this doesn't pose a big problem.
Also, I don't know very much about Linux, I have installed it a couple of times and fiddled a bit, but nothing really advanced.
