My personal favorite BBS is Wasteland. Pistolgrip (sysop) lives nearby and runs a great show. He puts a great deal of effort into his system. You can access it at wasteland-bbs.com via telnet or HTTP.

Also, I discovered that MultiMail is about the best reader available these days. It's available for *nix and W32.

Finally, Synchronet has been released for *BSD and Linux. It's probably the best BBS software out there and the CVS repository is updated daily.

UPDATE: Wasteland has been unreachable for the past two days. I suspect the sysop is travelling for business purposes and has no facility to remote in.
