the yahoo idea is a good one..I've not familiar w/ it but I'll give it a try.
I would also suggest maybe a giveaway or 2 from our sponsors? Like a free products of so much or free shipping or decent disc or something for that nature..that will bring peopel but also state a criteria of being an ACTIVE member on the boards. not just joined to get into a giveaway.
Tell as many people as you can about the site a word of mouth is one of the best means of spreading the word about something.
Have you thought of bz cards to sned out to peope that are willing to distribute them??
Just my $.02...
