Owomano...also, it's best for you to begin using your own apple ID when you buy future apps. It'll just make it easier for you in the long wrong. Just remember to log in and out with the proper ID so you don't lose anything with syncing.
Skimonkey, pls I think I still need ur assistance again. Pls iMessage is activated now on my iPad. But each time I wanna send an iMessage to a contact who uses an ios device, the send button is not activated to send the message
Do you have the Subject Field part of iMessage turned on? You might be accidentally typing your text message in the subject field versus in the actual body area of the text. So, check to see where you are actually typing...?
