MSN conversion logging

[smokedog]

If I'm working in a company where Internet connections comes from the router via the server. Can my MSN conversion be logged on the server?

Any programs that blocks this?

Short of rewriting the MSN protocol to use encryption, no.

So this program doesn't work then?
