You asked, so don't say I didn't warn you. LOL
I've seen some boards that have a "points" system to encourage participation. Various prizes are given like custom blinkies (have I mentioned I'm a new blinkie fan?!), goodies, or advertising slots. One place let you have a customized title. I want to be Romance Goddess.
How about a space for authors to host a day or week here? Or author groups? Or Publishers, for that matter. Not something that they'd do forever, just an event that would attract readers and authors for a day or a week. Maybe draw more people to the boards?
Ok, I'm out of ideas. I need lunch.
