FAQ Section Coming Soon! What should it include?

Hello everyone! I’m working on creating a frequently asked questions section for our forum in order to help new members and established members as well.

What questions do you think would be helpful to have answers to for new and returning members alike?

Some ideas I have so far are:
How do I tag someone?
How do I let an admin know I need help?
How do I label my posts with relevant tags?

What questions would you add? Remember, there are no stupid questions!
