Greets, macgregr...
I took a look around, but now that the tdg.nu boards are gone I'm not finding anything pertinant. Sorry.
I'd say your best bet would be to get into commos with Curt Chambers (program author) aka Raindem, either by pm or by email. cmchamb@comcast.net is the only addy that comes up recently.
We can take this to email ( mine lzard AT verizon dot net) if you wish, as while I've yet to attempt much more than some minor graphic mods to already published scenarios, the subject is sure to remain relevant, eh?
I've noticed your pleas for help with the editors, and wish I knew something that would help.......
Sorry!
