People can play together. Our player base here is so small that you will frequently sit with the same players, even more so at the higher tables which only a small percentage of the population accrue enough points to play at.

That being said, they can't be playing as a team in every game. Trucing in-game is fine, but some players clearly are always working to help a buddy, and that's against the rules.

The tools to "prove" this don't exist, so unless a mod is there or someone takes a video, there's not much that can be done. Games aren't recorded automaticaly, unfortunately.

And if a mod is there, changes are good that nothing's going to happen anyway.
