Suggestions on usability
1. Place a link on the General Messages main page, to Non-Tennis. And Vice Versa. Would be good if these were just one click instead of two, as I go back and forth often, and imagine others do.
2. Put up a flag in the header area when new bet items have been listed. When the day's bets are not up yet, I go in there many times checking, then back out, then back again in a while, then back out, etc. Would be nice for everyone to see that in a flag up top.
