DO YOU KNOW THAT?

Bbm has TIMED MESSAGE.... Where you can give a particular number of seconds any viewer should have access to the message you sent to them.

MESSAGE RETRACT FEATURE: you can take any message sent to anyone back immediately or later if you dont want them to have evidence against you or such chat history.

PRIVATE CHAT: Bbm has an avenue for chatting without record taken. In private chat, leaving the page to normal chat page clears the whole conversation you've had, and you got to start afresh if still interested in private chat.
