You mean their ID on this site? Or gamecenter? If yo know their ID here then post something on their message wall, even if they don't check it that often, they will probably get a notification email about it, unless they turned them off.

If you don't know where a users message wall is located, try:

dragonvale.wikia.com/wiki/Message_Wall:

just insert their username.
