futurekid's original league. Perhaps not the most complex/wacky thing ever, just a team twist (plus one free agent) league... but it has it's own
web site, has been running for 25 seasons, and the Owner's Forum is always active and entertaining. It's one of a handful of leagues I still religiously play. Maybe one day I will actually win a World Series there. Sad as it sounds, after 24 seasons (I missed season 1), it's one of my main goals in life.
