This would have to be the best idea I've had in a while
Site donations are cool, but I'd like to suggest an extension to this idea. Member donations.
It would work similar to how vb.org handles the "Support Developer" - Click on support developer [DBTech] vB Optimise v2 (vB4) - vBulletin.org Forum
1. It would have a similar usercp set up like vBulletin.org Forum
2. User group permissions. Set which user groups can enable Member Donations.
3. Integrate it into the footer where you have Contribute. Make it work as a pop up like on vb.org
4. Have a member contribution stats page. This page will outline which members have received donations, and how much they have received and when, and have it ordered from highest to lowest.
Why? Because if I enable this feature on a certain user group it will 1. Entice people to join that usergroup. 2. Make people want to contribute more and improved content. Overall this feature will make the community more active, and that is a win win.
