Just a point but havent you got to consider that the name will crop up in a search engine if a prospective new PLer types in, gamble or tip or whatever?
I suppose youre looking for something that reflects the gambling tipping side and the community side as well (for which, thesportsbar is probably a good name)
My suggestions are (obviously they'll be all one word or hyphenated)
Gamblers den (or the gambling den)
Gamblers corner
The tipping network (i like this one
)
or the tipstersnetwork or Thegamblersnetwork
Komps Wanking for Profit
Good luck.
