This is their message though:
IMPORTANT: Yahoo Groups has been very unreliable lately. We will do our very best, but there is a good chance that we may not be able to transfer all of your messages, photos or files. We will tell you which ones we were not able to transfer. Also, the migration queue is several days long at this point. Please be patient as we work through the backlog of transfer requests.
We'll see how it goes. In the meantime the new list is active and ready to go.
See you on the other side.
Roy
