To get the forum active i think it should have a different layout such as:
(clan VeN)
Clan Battles & League
Clan Discussion
Replays
Graphics
(recruitmen)
Want to join clan VeN?
(Warcraft talk)
Arrange team
Strategy's
off topic
This is just my idea for a forum arrangment, i think if we have more categories like this the forum will be a lot more active. i can also make graphics for the league topics and clan battles.
