Something weird has happened and I wonder if anyone has had the same experience: When I logged into my acct this morning, almost ALL of my email messages had been moved to the trash. I had to go into the email trash to pick out ones I wanted restored to my Inbox. Even my REPLIES to emails that I'd sent over this past weekend were completely deleted, aka gone foreva! Are the owners indiscriminately deleting our emails to clear space on their server? I find this disturbing: we have 3 paid lifetime accounts.
