tonyh Since this is a game server that encourages community along with the games, there is no harm in opponents playing out their games or even having friendly chats in the face of definite defeat.
Since BK offers no doubling cube for backgammon, it's really hard to take the game too seriously here. Backgammon with a doubling cube and backgammon without a doubling cube are two entirely different games. Add betting and money to the mix, and you've changed the games even more.
If I find myself in a hopeless position in a game, I usually congratulate my opponent and tell him/her that I'm going to resign on my next move. This avoids a lot of misunderstandings and keeps the tone friendly. If I have mathematically won a game, I never ask an opponent to resign. To me it's really rude to ask that of someone. They may want to have some fun by learning from you.
Being a member of a gamesite such as BK is more than BKN ratings and amassing numbers in one's win column; it's social games and community.
If you're obsessed with wins and ratings, a BG site such as FIBS is probably better suited for you than BK.
