I remember we had raffles in the old days on the forum. I think that was fun. That is a great ideaTo try and get more members, why not have raffles or something (don't want to say freebies) because people shouldn't be out of pocket, but we need something to entice people over and give them a reason to come, by doing this hopefully more activity will follow.
But a raffle for something, even if everyone who enters pays a £1 or something to cover the cost?
Anything extra made could go towards running the forum or reinvested for the next raffle.
Maybe then you could get sponsorship to help fund raffles to for advertising?
Just a thought.
