pB: i agree that the time per move is a bit vague with the option of weekend days and vacation days added ... if you really want to be naughty you can even switch your weekend days while playing giving you 2 extra days once in a while ... just to frustrate your opponent :-)

about players knowing what they signed up for ... maybe they didnt know at first ... but i believe people learn from experience .. or at least i hope so ... and after some tournaments which are too slow for their taste they will think twice before joining a tournament which might be slow

due to a busy real life i am retiring on this site, and also on dailygammon, just finishing my running games/tournaments ... which migh take years, but i cant stand to lose on timeout :-)
i am only playing now on jijbent.nl (i think the english version is yourturnmyturn.com ?)
i think there the default for tournaments is 1 day per move, and a max 6 day pool
even then tournaments can take quite long

you are/were quite active on dailygammon as well .. what do you think of the timecontrols there ?

out of curiousity : about how many players are we talking who "abuse" the time control on this site ?

if i have an opponent who plays too slow according to my taste (rarely happens, but sometimes it does just before i go on vacation) ... i then send him a polite private message asking him if he could move in my games first

if an opponent sends me a message asking me to move faster, i then make sure i always move first in his/her games before i move in the others

about the speed rating per player: i suggested this years ago as well as i think its very useful and very informative .. but you have to take into account the different game types .. an average speed would make less sense that an average speed per game type
