I have 2 Macs running the latest OS and the latest TB with pop accounts. I would like to copy a folder (with subfolders) of email from 1 Mac to show up and work with TB on the other Mac. I am going on a trip and would like to bring those messages (perhaps 100-130) with me. I do not want to replace anything else that is on either computer. I want to leave what is on both computers in TB and just move one folder to the second Mac. The mail is all gmail but it is not on the server anymore - messages are locally on the 2 Macs.
