Was tons of BBS programs for the Amiga. The main commercial ones were:
DLG BB/OS, CNet, Excelsior! BBS, Xenolink, Zeus BBS. With the exception of Xenolink, most can still be found to download in a free or cheap form. Was tons of shareware ones that got a lot of use as well, like AmiExpress, Max's, TransAmiga, DayDream. Personally, I never liked any of the shareware ones in the least, and the commercial offerings were always the most popular on this side of the pond.
I've run E!, Zeus, DLG, and CNet quite extensively in recent years and all still work very well for running multi-line telnet BBS's. I use a heavily customized setup of Zeus these days for my BBS on my SAM, but should have DLG converted over to OS4 one of these days and plan on running it with MM/GMS.
Source and binaries are available for DLG via Aminet. CNet, E!, Zeus info can be found via a Google search. As far as comms programs go, I was always a fan of Terminus, but there's a wide selection via Aminet.
