Sorry you lost your post. Did you click the remember me square located where you log in. At first I thought this meant, 'remember my password' but I soon realized it meant, I would stay logged in if a post takes a long time or you get busy with something else. I lost a few posts myself and understand its frustrating. You can also copy a long post just to be safe. Log out and re- log again and click the remember me box. Hope this helps.
