... However, i have no problem with slow players as they are following the rules.
I guess my interpretation of the rules differs. Vacation is to be used for vacation. To me vacation is when you are away from your computer and cannot make moves: a planned trip away with family, a death in the family, illness, injury, business trip, etc. Vacation is not for extending that three moves to four or more every move or two just because you can't bring yourself to end that hopelessly lost position. People do this and it's sad.
I have read quite a bit in the forums lately of slow players (via the use of vacation time usually).
I have heard interesting arguments on both sides. Personally, my move speed is around one move/hour (the joy of working at home). However, i have no problem with slow players as they are following the rules.
The argument I would like to submit is that slow players should motivate the less patient players to find quick, decisive victories in won positions. Indeed, if you can find a 4 move forced win over a 12 move then this could literally save you weeks of impatience.
Thus you can use the slow players speed to your advantage and learn at the same time.
