we take the people with the lowest avg time per move first...
I am actually working on trying to get my avg time per move down. I have already decreased it by over an hour in the last 2 weeks because I finally got an internet connection at my house. I am now checking my games several times a day to reduce that time.
A lot of my greeter games timed out: and at one point the system suddenly gave me ten games at once, before I learned to limit the number. I've made friends, though, with a couple of players who've played right through to the end, and we have rematches going on (for fun!).
