SabreFans.com - I like the site. And theres alot of awsome posters on their message board, but i just hate the way their forum is layed out which is why i never post there but only read. Also Josh Mora posts there.
UltimateSabres.com - It's alive and well. They have a very solid message board with tons of posters. They recently "signed" a partnership deal with www.billszone.com which is a huge Bills fan site and the UltimateSabres.com people don't know if they should keep the name or change the name. For now, UltimateSabres.com is down, however, you can access it at www.SabresZone.com but theres a vote right now on which name to keep. If SabresZone wins, i bet they will do a new layout and all.
