My users gets Points for participating in my community (forum, referrals, adding reviews, photos etc) - they can buy things in the virtual shop or put them in the virtual bank to gain interest. I notice people are getting involved in making more and more MODs for the points system (lottery mod | quiz mod etc). So here is my idea of what would be a great add-on.
I'd like to see a MOD created where users can invest their points in admin-defined virtual stocks/shares. Other sites do this but not very well cause it isn't integrated with a community feel. http://www.popex.com
For example if you have a Sports Site you could have stocks for Liverpool | Man Utd | Arsenal | Barcelona | Real Madrid etc...
If you have a music site then Oasis | U2 | REM.... well you get my drift.
Based on the real 'but not much fun'
stock market - shares go up when people buy them and go down when people sell them. It should also be possible for mods/admins to mass adjust shares based on 'events' - such as a team beats another team, wins league/cup or a band announces a tour or reaches No1 in the charts.
Its quite in-depth but Its quite simple really. Anyone interested just PM me.
You can have it all if you like... but you can pay for it the rest of your life.
