vacation

I'm a bit confused about a topic called vacation. I play live chess, games ranging from 1 to 30 minutes max. Does it mean i have to play each day or else I will loose my site-rating ?  What if I dont want to play for a few weeks ?

Or does it only counts for tournements in which people can do several days over a single game  (like the old play by postmail) ?

You're rating only varies according to games played, so no worries if you don't play for a while!

The only thing that'll not playing for a while may effect is your RD, which goes into how many points your rating will change wif you win/lose/draw. The more time between games, the more your rating will change/game as it's not sure if you got better or worse in the time you didn't play.
