A friend and I were thinking of getting together and creating an NL-only auction league. It would probably be 12 teams, and 5x5 roto, and I was just seeing if anyone was interested in here. I think the buy-in would be around $50.
If you are interested, either PM me or send an email to email@example.com
If we can get people together, we may try to start it up at mid-season or something, with a little smaller buy-in.
It will be a keeper league, and we'll try to hammer out those details later.
