I've read a lot of comments that they take forever, and if you did something stupid like I did (forgot my password and had to reset it) they will hold the transaction 24 hours before they send it.
Thanks for your response. I have the transaction ID from Cryptsy to confirm it has been processed. Should it still take 24 hours after that? MintPal was quite quick...
Someone above, I just read, also remembered that you have to confirm an email, did you do that?
