I've got a transaction from Slush's today but its status is "Seen by 4 peers. Pending/Unconfirmed"
It's been like that for over 5 hours, dunno what I can do about it.
Wait longer

Its nearly 24 hours now, how long would you wait, and is there even anything that can be done about it?
Guess its just wait and see, it appears some people jipped on the transaction fee so now we all have to wait.
