Well, you got this post through, maybe there was some kind of glitch (professional technological term for anything awry) in the system?Can you try again?
I learned this trick from my computer savvy husband (system analyst go figure) and next time you type a big long post, highlight all your text with the cursor and then press control and "C" at the same time. It will save your text if it doesn't go through and you lose it. So you start over, pull up the post window and press control "V", and voila! all your text is on the page. Commonly known as "copy and paste", lol. It will keep the same text until you do the same thing again with some other text. I hope this makes sense??
