I have a mailing list on Thunderbird for both my local community service club and one for family news. I have used these lists for years and years. However, last night when I tried to send out an email to the community service group it wouldn't send. Upon further investigation, I found that the list was now empty - no emails were in the list! When I tried to add them back in and hit "ok" they did not stay on the list - just disappeared! The same thing happened to my Family List, but not to our Beekeepers list. It seems they would all be gone, but some are gone and some are not! Is there any way to get this to work again? I set up another list for the Community Service group with a slightly different Title, but that wouldn't work either. Thanks! David & Renee
