Thanks everybody for the fast opinions. I love them all.
As I can find out from your opinions, this domain is saying: "Develop me!"
I will definitely do that.
I know I've maybe paid a lot for it (competitors were still bidding on that) but I was thinking as bm****** stated above that Keyword+forum has always been a good combination for online community websites. So probably, as alan***** said, I've paid an enduser price, so better develop it.
Considering what online casinos pay to affiliates and reading stories of successful people making $$$$, well, I will give it a try.
