Have you ever accidentally necroposted?

When I was new, I wanted to respond to all the things, so I went through multiple pages of threads before someone said something about necroposting. That was when I realized I'd jumped into a thread that had been dead for years. Whoops.

I was really glad to read the official rules recently. Apparently what I did wasn't against the rules, just maybe annoying. I really was trying to be part of things.
