One thing though, bringing people (especially those who become active) to 2S will get you rather lovely numbers of points. 
This depends on how many/what time the pointsmasters (or whatever we decide to call them) are prepared to put in to calculating such points.
What we could do is say if you bring a new member to the forum, you get a certain %age of points they get added to yours as commission, in addition to the points bonus for a new member. So if he writes 5 articles for, say, 50 points - then you yourself get 5 points (10% commission) because you're the reason they are here. This %age of commission isn't deducted from the rightful person that scored them, more added in addition for the player who roped them in.
Therefore it's more rewarding for a current member to get a few players with a real buzz for the hobby in, then it is for them to just force all their facebook friends to sign up with a profile and never view the site again

Another idea could be to host smaller campaigns within campaigns every 3 or 4 months or so. Say for example, the past guard vs ork campaign. Points in the sub-campaign (perhaps come up with a better word for it in future

) will be tallied in the subcampaign (for relevant articles about the campaign, etc) while also claiming the regular global points. Then, the winning side (order or disorder) would get a large amount of points towards the global campaign for winning a sub campain. If that makes sense.
Another idea I had is why not limit it to order and disorder. I know, especially with disorder races - they'd like to see where they sit on the ladder of disorder, who to bully on and who to look for allies with, etc. I'm sure the Order factions would also compare for their own cocky and ego gains. So aside from the main global Order v Disorder scores, each board/race/faction could have a subscore - used more with campaigns that involve multiple parties, etc etc.
We could also look to include some vassa......erm...online games.....with the forum members. This could allow some games to feel like community games for a change - could prove epic in terms of campaigns, etc etc.
Just a few ideas
