To get in with the crowd. Well basically just help out on the forum with new people from your knowledge... Get in to games, discussion, updates and helping others. Make some friends in the game and on the forum. Really to get noticed on the forum is to post and help a lot. Also you could create maps, markings, items, meshes, et cetera for others and that could make you more into the crowd, too. I'm not completely understanding that project either, so don't get too involved if you ever do.
Belong with the mods? If you're talking about becoming a moderator that is one big honor. You need to be active on both game and forum, most of the staff and a lot of the community likes you, you've helped out for the game and forums... And you have to be a certain age. But if you're talking just to be with them I'm saying just... you could meet them in game or personal message them and maybe make friends with some if they like you. It depends. Just don't go out there acting like a moderator, mmkay? x3
Good luck out there.
