I don't think he is joking I will also recommend Bitcointalk gambling section as the best place to interact to anything related to casinos and gambling discussion.
Anything you want to know about gambling and particular casinos is all here; you should have posted that besides Bitcointalk so members will recommend other communities and groups, but so far Bitcointalk is the first thing that will come to mind when looking for groups or communities.
I think what I understood by op is that he is looking for group or community where to share some form of links and or place where he could easily get some games to gamble. But however, any discussion that is about gambling can be gotten here as it carry's much information pertaining to gambling addiction, and all forms of relevancies.
