OH DEAR!

And we need to chat on one of these services to exchange homework and the like.
If it is homework, why don't you do your own? I used to when I was at school

If it is pr0n...............go find your own.

You only "share" with people you TRUST and trust implicitly. You obviously don't trust this guy, so don't share.

If you are exchanging things, you are wide open as suggested..........sure your IP addy may change with each logon, but you will already have been backdoored..............if it hasn't happened by now?

Like I said..........trust
