I'm thinking of offering a prize for a yet to be defined target for user signups and/or posts. Say for example - and it is only an example - the 250th user to sign up, or the user who posts message 5000, or summat like that. I'd appreciate suggestions for:
a) Prizes. Should be small and affordable, but something that would be appreciated. Unusual and/or funny for preference. Something I can brand would be even better.
b) How to avoid it being abused. If I post an announcment, people will sign up under new handles or post like idiots, which I want to avoid - I'm not going to skew figures for this site.
