bizMP forum - Buy/Sell Sites and Domains

At bizMP forum they've set up an MarketPlace where you can buy/sell domains and sites. Trading is free and accessible to all members. Interested members and good offers are needed so they opened a big starting posting/referral/advertising contest.
Post brings you one point. This is set low if they expect decent posters.
For a good referral you get 50 points.
For a blog announcment of the forum you get 100 points. Google lists blogging sites high, especially their own Blogger. Post submissions in blogs became a business just like link submissions in directories. Besides you get 100 points for a 500+ words webmaster article. Three winners get $1000 each on PayPal after the end of contest (December 15th).
