It would be good to have a little news ticker somewhere on all your pages.
Ideally, this would should info regarding new tournaments which have been created (I always seem to miss these) and admin announcements. I can't really think of any further uses atm, but I'm sure lots of very useful, relevant info could be shown.
It would be even better if you could personalise the news items that u see. For example I only have interest in 14/14+ tournaments, so maybe I could select these tournaments as being the ones that I would be notified about. That implementation isn't very important though.
