horus:
What Lone Paladin said. I tend, when I'm working very long posts, to paste them into a text editor every so often.
What Lone Paladin said was smart, but I already tried it, and it didn't exactly work, because I didn't realize I'd made the mistake fast enough in the first place.
But what you're talking about SORT of helped, Horus-- I realized right before bed last night (but after I'd turned the computer off for the evening) that I should check wordcounter.net, the word counter I often use online, to see if I'd stuck the text there to help work with it, as I often do, because wordcounter.net saves things forever... UNTIL you come back and paste over the last thing.
And it helped a lot-- I didn't get back everything I wanted, but I was lucky enough to get some of it-- at least half of it, maybe a bit more than half, I think.
So... yay! I'm better off than I was going to have been otherwise!
