Been a member of sports boards since 2004 and it used to be quite active. Really good posters still over there even if things died down a bit. I'm on sports hoopla also and have to say it's pretty nice over there. Don't know how many of you have been on chicitysports but I'm there too and it is a good source of info but you have to get through a bunch of peoples crap and ignore it
My sig is a pic of Alyssa Milano in a Bears shirt.
I'll tell you one more site you should consider: Sports-boards
Many of the folks here used to post there (some still do.)It has a very small set of mature, experienced posters some of whom would be familiar to this board. The platform is vbulletin, the same as this site. Culturally and technically I think it is a really good fit.
In fact, I think it would be great to get a movement of the entire KFFL message board community over to SB.net if possible.
