kind of tell how many posts you'd ever posted on MN. Or summat - the precise details escape me. Or it might have been an index of prolific posters.
I don't know. But is it possible? I know you can search your posting name, but if you post, erm, rather a lot 
you can't tell how many words that is, short of cut and pasting them all into a word processor. Which would be bonkers.
I want to shame myself into withdrawing for a while. I write so many words on here, I reckon I could have written a couple of novels and academic books by now. Which is bad and I need to be more productive instead of pretending this is useful distraction...
