what happen to our topics?

what happen to our topics some time after they were posted?
i have been out for like 5 days and now i can find my old posts :? :? :?

go to search at the top, enter your name, and the name of your topic

You probably can’t see them, becasue people made other posts witch made your go near the bottom or on the next couple pages.

The post is probably back a couple of pages, as calanel said use the search bar.
