Umm... I know people have gotten all tied up about the retrochallenge around here (and that's good) but in order to participate without a heap of hassle I kinda would like an answer to my question: does anyone know (BBS Sysop?) what kids of terminals the BBS can deal with other than the default VT100? Is there support for limited display sizes?

If changing things is an option, I would recommend taking a lead from the guys running StarTTY and let users choose their columns and rows size for their account.
