You don't need to close every topic!
I've recently noticed that quite a lot of people have been asking to close topics.
First, you need permission by the creator
You need to ask the creator if it's ok to ask for it to close! So they understand why suddenly you want to close the topic!
But that was just a point...
What I wanted to metion is...
Just because the question was answered doesn't mean that the topic should be closed! Some people might have the same question! So they can simply search using the search button to find their answer in YOUR topic!
Thats why you shouldn't close topics!
Also, sometimes people forget to SBYP! They might make a cool tutorial that's already been made, but it shouldn't be closed! It's still helpful!
You can also recycle!
If you made a topic that's for a test or something, you can recycle it not close it! When you need another topic, simply just use that topic! That way the forum is not clogged!
