Doesn't anyone out there have an Apple computer besides ME?

My brother who lives out of state just purchased an Apple desk top and I have an Apple MacBook Pro lap top. I offers iChat which allows two people to communicate through video/audio in real time. It is supported by AIM and MAC. Last night we were able to send and "invitation" to chat to each other, but when we click on "accept", we get a communication error.

Does anyone out there know if that is an Apple or TW issue?

I revisited the Apple support discussion forum and they said that it was a problem with my router. So I called TW and they have a MAC specialist there. They walked me through a process that would open a port in my modem/router combination.

My brother may have to do the same if we can't connect tonight.

I love my Apple. I would never go back to MS.  Popular Mechanics just did a comparison of PC's and MAC's. MAC  They preferred a MAC, and so do I.
