not in any specific order:
-contests (best post, most quality posts, 'name that tune', show us a royal from ur game, show us X-number tourney wins, etc etc)
-freerolls (preferably on pokerstars, heheh!)
-forum league (freeroll or smallish buyin or combo of both...say 10 games or so in 10 consecutive weeks...again, preferably on pokerstars!
)
-random $$ drawings (nothing wild, just a few bux here and there)
