high stakes cheating ?

sketchy!

In the good old days of bad old connections, t in the chat would usually mean "testing I'm connected" if someone thought they were suffering from lag. I think t can also mean "true, that" in a chat conversation, these days.

t

This isn't evidence of anything. I have done this before simply typing up a note and accidentally putting it into chat.

Especially likely if you have it set up so that table with pending action is set to pop up.

some damning evidence of super usering right here!!!!
