BBS Software for Unix?

Walter Bell asks: "Several years ago I used to run a BBS based on the Oblivion/2 software. Obv/2 was an excellent BBS manager, but as far as I can tell, it is still only available on the MS-DOS 3.3 platform. Does anyone know where to find a Linux port of Obv/2 (or any other Forum hack, for that matter) so I can start up my BBS again under Linux?" Ahh...good old Forum. I remember hacking my own copy of Forum and producing a clone called Apex, back in the day. Have ports of any of the old school BBS software platforms ever made it on to Unix? I do remember WWIV was C, so that may have been ported. Not so sure about Forum, however.
