And I was accused of attempting to get on the server from my IP....at the same time a post was made under my user name by semeone else...yet there's no possible way that someone could have been using my wireless network without my knowledge. It doesn't reach outside of our yard. I've tried numerous times with different machines.

I'm thinking the problem is on the Agtalk end if this is happening to multiple users. Sounds like the system has been breached to me.
