That doesn't really matter to much. I have seen moderators get accepted with as little as 150 messages I am also on the forums everyday for a few hours :P
Try and get messages though That is very true, now don't post farm just go to the help section etc...
As I have said, I have seen moderators get accepted with as little as 150. Also I believe I am ready to undergo this position. I dont believe messages matter to much, as long as they can do the job good @Herf @Stacker7
I know that but still messages shows your activity with helping people, reports, and all of that important stuff if you do not have much people will think you are just inactive or do not do reports/help anyone.
