That's just it. If I didn't subscribe to every thread I ever post on, I'd never find them

. I am even subscribed to some threads I never posted on, just because they had links in them that I thought I might want to refer back to.
And actually, I rarely need to go back and even look at more than just the first page of my list. But occasionally I do, and I'll even go back several years to things I posted long ago.
I don't understand why people don't subscribe to threads and then complain when they can't find them. (I don't mean you, Papa Deuce.)
ETA: I do turn off e-mail notifications if a thread is getting a lot of posts.
