You may have heard the rumors, or some of the admins grumbling about this, and the threat of some servers splitting. In the end, it was agreed upon by both networks. Undernet, the original offshoot of EFnet back in 1994, has once again agreed to to become part of EFnet, or, as we are to be known, EFUnet.
Most of the charge on EFnet's side was led by the US admins. The EU admins promised that they would also try to get IRCnet back in the fold.
The servers will connect sometime today. Be on the lookout!
