Normally in correspondence chess when you announce a vacation you say when you are leaving and when you will be back. During this time, your clock is stopped. There is usually a regulation on how much vacation you can take during a year.
On this board however, there is no stopping of the clock during vacation. Unless you have a laptop with internet access while you are on vacation, you can come back to several lost games....many lost games if you are playing a large number.
An improvement to the site, in my opinion, would be a way to stop your clock while you were on an announced vacation with identified start and stop. Your clock would start running again when you made your first move after vacation start, or upon vacation stop. The vacation time could be accumulated to some limit during the year thus affording us an opportunity to take a "vacation"!
Thanks for listening.
