Spent an excruciating amount of time today typing out a thread post. I'd had another tab opened, was researching links and whatnot to post in my response... One thing led to another, and I fumbled! Yep, lost my stuff, gone, kaput, zip.
I was devastated, but have been noticing the yellow "auto-save" thing popping up in the lower right corner of my posts... Took me a minute to find the way to retrieve my post, but finally did!
If you lose a thread post, re open your response option, and look lower left, below the space for typing your response. There, appear the magic words:
Retrieve Auto-Saved Content
Or something like that....
Many, many THANKS to the genius who thunk THAT one up!
