I don't want to add features if it's annoying but I'd like some help recruiting members, so how about a referral competition. When the plugin is enabled you will get a referral section in your profile where you can copy your unique link and see who registered using it and so on.
I was thinking that there will be three prize pools of which there will be a random draw in each pool:
1 referral = 3rd prize pool
2 referrals = 2nd prize pool
3+ referrals = 1st prize pool
Need to check what I have at home that's worthwhile to give away but top of mind a choice of things like a jar of weed, a mobile credit card machine, anonymous mask, cool unused shirts and other random stuff... or maybe some cash.
Thoughts?
