How about if chat windows could maintain conversations, like . I wonder how demanding that could be for the servers. Maybe just giving the chance to "keep this conversation".
I would like to see the option of two competitions at the same time, or maybe overlap two competitions so there is always the chance to participate in one, and choose the one you like the most.
