[JDEV] how can I clear an offline message before the user comes back.

[Dixon Canario]

Can anyone Please, Help, 
and important for any developers...


    You know how jabber retains the message when a user is
offline
Well I like to know if you can clear the message from the
server before the 

user comes back. Like here's an example. 
Let's say:
 	" I'm the one who send you the message and I want to
clear it before 

you come back? "

    Can anyone tell me how can this be achieve?

Thanks,
