Get ahold of Toad of Toadville. He uses Synchronet on his games, and he should be able to help you figure it out. his server is at
telnet://toadville.dns2go.com he should be able to help on the Synchronet hook up. You should use the RLogin in config on the TWGS for the BBS to log Players in from the BBS to the TWGS.It will use their login to the Synchronet to the TWGS. I hope this helps you in finding out how to hook it up. Toad should know for sure. If the server is not up then go to his web site and Email him. Its in Google.
