Hi Eion,
   Thanks a lot for sharing those.  Really really useful to me.
"what chat application" . Am really sorry I am not in a position to reveal
that since its not yet out. I will inform surely once its out.

For now I will go through the source codes,
As far i know, i ll have a directory
 pidgin-2.10.0/libpurple/protocols/MYChat and will have my code.
Can you please advice what my Makefile should contain

Thanks
Karthik.
