If you suddenly can't send email with Comcast in Socal
 

Comcast switched me over to Time Warner's roadrunner service without telling me and I suddenly couldn't send email. If this happens to you PM me, or post here, and I'll walk you through what I had to do. I sat on the phone on hold for 1.5 hours before I spoke with someone who helped me out. BTW, your email is going to change from joeblow@comcast.net to joeblow@ca.rr.com

too bad for you. When Cox was on road runner it was aweful. The connections to the servers would be constantly out. I hope for your sake that they have gotten their act together since then.
