"Fencer might redo all the ratings with a better rating system and fix everything up to this point. (then again, maybe not - but we can hope.)" yes we can hope
alanback: i think i kind of missed your point. i just thought that you couldn't resign and lose (just) a gammon even if there wasn't any contact and you were clear of your opponents home. then i found the game i posted as an example for the possibility to do that. but of course, if there is contact you can't resign and lose just a gammon.
nabla: yes, that's how it's done. for some reason i thought the resign-function was messed up on brainking. (and never resigned in those situations) but i found an example of it: Backgammon (kd5svqJT vs. saeco) but do you actualy lose a backgammon for a timeout even if it wasn't possible to lose one if the game was played till the end?
playBunny: iirc, you can't resign and lose a gammon. i think that a resign means you lose a backgammon as long as you haven't moved out any piece - even if a backgammon would be technically impossible at the time. of course the option to resign a game as a gammon would be good, but i don't think we have it here.
