Ok, so at least in 1 topic you have seen people say "search before you post"
I'm going to show you how you can make people not say that!
1. Use the Magnifying Glass
You can search up posts and topics to see if your topic is needed a second time. This can also search up posts that may relate
2. Ask a Leader or Mod
Trust level 4+ can fuse topics that are similar to other topics. Tag one of them (or all) and ask to fuse the topic.
3. Think About it
Will this be helpful? Would this already be used?
Think about those things. You can use 1 if you don't know.
