Hi  Betty, Welcome..like everyone else said ..you will love it here.  I went through the frustration of  lost post. If it helps I will tell you what I do. First  make sure you have it on draft mode

2nd If you want to type directly on the area that creates you post  submit it when you are 1/2  way through..then edit come back to the original post and continue.  I do this a couple of times..write submit comeback  few more lines  I keep doing this until the post is done.  If you do not submit you will at times take the chance of everything you have written will disappear.   I do it that way because I just can't stand to do it the easy way...it is just me....the easy way is to write your post in word or notebook then cut and paste to where the post is placed to have it read by the  HTML code.  I sure hope this doen't confuse you more......It's fun....and again  Welcome
