I don't know if this was a reddit feature that I missed, I'm not going back to check, but I only figured it out the other day. If you hit save, you can make your own custom tags for threads so you don't lose important stuff. With so much great stuff being stickied it's easy to lose stuff and not be able to find it again.

I assume I wasn't the only one who didn't know this. Or maybe I'm a moron.
