Hey zep...I did it, I did it! I really did it! :) I can send and receive from each account. Each AOL screen name has to have its own account set up with proper port #s, matching user names, etc. raven, you're right...I just had to keep digging around. I found a Mozilla forum note from 2006 where someone had done a good job of explaining. Thank you again for pushing me on. Pam

Thank you, everyone. Raven, you hit the nail on the head...I wasn't using my regular AOL password. DUH. :) It works perfectly! Thank you, daylilydazed, for the heads up about checking the web AOL spam folder from time to time. This is such a great group of people. You are willing to share your time and talents and it is greatly appreciated. One more question. If I wanted to add my husband's AOL screen name so he can use Thunderbird, too, do I just go through the same steps I went through to set up the account? Is creating a new email user the same as creating a new account? Thank you. Pam

I use version 2.0.0.4 which is the latest. It's under tools > account settings > server settings.

The answer to my second question is this... Earthlink has been trying to phase out a particular server for years now. You need to access your server settings via account settings and change the server and port assignments. Problem laid to rest... ver 2.0 installed
