What is necro posting?

Question

I've heard this term in forums,but I'm not quite sure what it means.

Answer 1

The act of posting in a forum thread that is too old to matter any more, or has served it's purpose.Usually by new, inexperienced members of the board.A common trait of someone necroposting is not to only bring one old thread back from the last page before deletion, but to fill up the entire first page with threads that only they seem to think have relevance to anything.
