Cool. Best of luck!
Started a Point of Sale support forum about 5 years ago. Started with some crappy posts. Pretty generic stuff. Never ranked well for anything other than POS Forum. Did a little SEO etc.
That term got me about 50 visits per month.
Then I started a new job. Abandoned all my sites including POSforum (dot) net.
Fast forward to 6 months ago, decided to really get aggresive. Started posting like a fiend. Did a ton of link building. New members started joining and posting. Now I make $300.00 per month on direct ads, about $100.00 per month on adsense, and about $75.00 per month on affiliates. Not bad, but I really need to get to the $5000.00 per month just off of that site. I get about 2000 uniques per month and growing at about 10% per month.
Anyways, thats my story
The earnings you've mentioned with just 2000 uniques a month is pretty awesome. Inspiring story.
I somehow barely manage to rake in $50 with adsense from one of my websites with 17k uniques a month. Ofcourse my average CPC is pretty low for the targeted keywords, however that's the main factor which makes the most difference

Most of the income is direct ads. I charge $99.00 for an ad on the right side of the forum (125x125) setup through a paypal subscription. That is where the money is imho, directly charging for ads. Adsense pays too, just not nearly the same...
