I'm thinking about starting an RPG club at my college this coming semester. What should I have to successfully start a club? What systems would be best for introducing people new to the hobby? How long should meetings run on average?
Well, first of all let me ask - is there a card game/board game club as well? It might be good to have some variety there.
I'd recommend some beginner one-shot events, probably using pre-written scenarios and characters.
As for things that might be a good way in, let me tell you this from my personal experience - AVOID 3.5. I'd also recommend getting rid of too many math-heavy things. Not necessarily no-D20, just go for something faster and maybe more narrativey. I found Mutants and Masterminds 2e a good compromise.
Variety is important, I think, so try to make sure different things are running fairly often - maybe keep the campaigns short and encourage a rotation of GMs or systems. Nothing worse than letting newbies think that there's nothing more to the hobby than D&D and WoD.
