I agree that a one week free Supporter every three seasons or alike would most likely encourage people to actually buying it.
i was mod in the german forum before, and had to admit that it was a pretty easy work. You normally don't have to read every upcoming post, but the normal mods are quite forum active so that some of them will catch nearly all insults(and if not, they also get reported).I never did the LA work before, but especially in the beginning is it a lot of work and also during the season you had to work a lot in a short time, and the LA tool is quite tricky since i at least chated with LA while they are worked on a translation ... Especially in occasion when they work, on a text which isn't released yet(like new season announcement) on english since they had to translate the text in small parts without a context. So they overworked it often after the release.
