Dear Classmates
Hi
As this tool (i.e. forwarding materials by email in yahoo group) may seem novel for many of us, I eagerly recommend you that be cautious & do not send any material that you aren't certain about it's origin & of course, any files that may contain virus, to others because this may disintegrate your home computers (you must note that any email from yahoo group MPH84, is regard by us as essential one & must be read, thus endangers our PC health).
With best regards
Iradj Ahmadi Araqi
