It seems to me that at the very least, a player in a tournament who cannot receive chat, but sends a message, should get an automated response from the system letting the person know that no reply can be received.
Since we're letting people display as a preference how much they're willing to pay for a tournament, it would be useful to be able to choose which such players to view. Similar to the box to "view only players online" i would like to be able to "view only players willing to pay their entry fee"
I often find that I find a new parter at a "partnership desk" and then I want to talk to the person about conventions. I resort to finding the person's name in the lobby, and clicking on that. Is there anyway to just type in a person's username to start a chat? Rather than finding some instance of their name to click on? (If not, there should be.)
