Bla Bla, you fail to understand that keeping your vacation in mind with timebanks needs the creation of longer timebanks? Games can last months while the timeout is only 3 days. To calculate vacation into timebank you either need longer timebanks or less games.
If everyone were to do that we'd either get huge timebank games running and slowing down the server more. Or people would take much less games wich can be a reason to stop subcribing (what's the use of being able to play more games if they will be timed out as soon as you go on vacation) wich ends in the site needing to shrink considerably.
