Skulls

People make reference to claiming skulls. What are they? Are there any other such terms on this site?

Skulls are little symbols in your games list which come up if your opponents time (and timebank) as come to zero.

If you click on it you will win by timeout.

In tournament games the timeout is automatic about two days after the timeout occurs (don't bet on that though).

Thanks, much. I thought it might be something like that.
