Put an ad in the Inlander.
Also, cheap, hand-made (not-at-all-fancy) flyers will stand out on bulletin boards around town. If you run to the grocery store, slap on up on there board. Anywhere you see a chance. All it takes is a sharpie and a piece of paper. You don't need the fancy graphic art stuff, there's way to much of thatnow-a-days. Plus it's free. Word of mouth is the way to go.
You have a great site and in time it will have a life all it's own. "Build it and they will come. Keep it too clean and it's boring. Treasure it like a sister and keep it safe." Keep up the good work. Oh yeah, I seen the ad in the Exchange, just so you know that that ad is working. I alsp passed it on to my Mom.
