add buddy to the buddy list

[Kamanashis Roy Shuva]

May be I should change the subject.

*My main problem is that I cannot find a way to send invitation request to
the chat servers to add a buddy to the buddy list.  *

Is there any abstract / protocol independent way to send this request ? Or
am I thinking wrong to need that ?
