Don't think it's possible to adjourn games here. If a live game hasn't gone 4 moves though and it times out, then it's aborted. Of course if you do that too often, you'll end up on Santa's naughty list.
EDIT: Surprise, surprise; I'm wrong again:

I'm pretty sure a game I was playing got adjourned because I don't see it in my archives. Wnere can I find it?
