CONTEST CALENDAR
I think the best way to deal with a contest calendar these days is a simple one. If you want more info on any contest at all, simply go to the excellent calendar maintained by Bruce WA7BNM here. From the looks of this wonderful calendar, Bruce must be able to dedicate nearly 24/7 to keeping it updated and accurate. I've used it enough to think that it must contain info on every contest that exists, and new contests are added as soon as possible. It's just a great site, and I congratulate Bruce for the job he is doing with it.
