I think you are wrong but I share the same feelings as you. Therefore, we are both wrong I guess.
I believe this site as well as other sites allows one to make moves even though they are on vacation.
All we can do is wait for them to run out of vacation tinme.
So one of my opponents has been on vacation for about three days and yet I have seen him logged on at least once in all those three days. One time his avatar listed him as playing live chess. I am all for vacation time. Life gets in the way BUT if someone is on vacation that would seem to insinuate they don't have time for live chess as well. Am I wrong?
