FEBL has 2 team openings, Harley and Star. We're a small league of only 16 teams and use fantasy rosters (and lots of other fantasy aspects). We have some unique house rules, but we've been around a long time (since 1998). We use OOTP5, and really don't have any intention of progressing to OOTP6.
If you like OOTP5, have a copy of the game and are interested in a league likely to be different from most of your other online experiences, drop by and give us a look. Feel free to post a note or two on our message board if you'd like to get to know some of our owners, or email me directly if you're interested.
