Board Game Arena

I agree this would be a very useful feature. For the fifth day in a row, I'm being bombarded by someone who continually messages me while I'm playing with other people! I mistakenly 'friended' him when we had a nice game, but I can't shake him off now...

I am having a lot of trouble creating this table too. Sometimes it loads up, sometimes it doesn't. When it doesn't, it still tells me I'm in the game, but if I try to join the game it won't let me. Once I even became an observer at my own table! What am I doing wrong?
