There are currently threads in the shot show forum from 2013 that people are actively responding to because they don't realize they are 2 years old.

Why not clear them out, or send them to archive?

Or maybe each year at the end of shot close the forum down and lock it but keep the content available, then start a new one for each consecutive year. I don't know how you'd organize them, maybe you could hide them and only show the most recent year, etc.

Just some ideas.

It's really annoying.
