Thankyou Myster.
That could possibly be the reason. I shall have to try to rememeber to save it another time. How do you do that?
If writing your post directly on site ~ when you think you've completed it to satisfaction... highlight all, then copy and paste it to a simple text editor such as Notepad. If your on-site post is then lost for some reason, say by refreshing the page or switching to a different page and returning to find it gone, you will have a copy in Notepad to fall back on and add to if necessary.
My method is to write in Notepad first, to get the content, grammar, spelling and formatting correct, then copy and paste it back on site. Others might use a simpler way that I haven't discovered, but being computer-knowledgeable I'm sure you already know this, Sadie?
Gotta dash... need to load my float with a thousand bottles of whole, skimmed and semi-skimmed ready for devilry before ten. That sozzled cat of yours isn't getting any of my cream tho'. See Ya!
