For 14 hours now Yahoogroups replaces msg author with group name; not happening to others
Msg folder for my yahoogroup normally contains user ID of sender in messages routed to me, with a separate field, Reply to, of my group name, USNA1957. Since late Friday night, the sender user ID is replaced with the nickname for my group "57".
Other classmates are not having this problem. When one replies to a message the sender information is correctly applied to the response.

tight click the folder, select properties and then repair, just in case it is an indexing issue.
Repair didn't work. This is a large folder; I'll clean it up and see if that helps.
I've seen other users complaining about this, but it doesn't seem to happen to all Yahoo Groups users consistently (or may be not yet).
In any case, this is a Yahoo issue and has got nothing to do with Thunderbird.
