Can I make a guide?

I want to basically write a forum post basically to help new users of the forums to understand how they could/should use the forums.

So basically some things I want to go over are like how to submit a useful bug report, getting help in development discussion, and just general forum things.

Is this something that the staff would disagree with me doing?

I’d say go ahead and make it. If the admins like it, they’ll sticky it. Otherwise the thread will just die in due time. It will also be interesting to see how everyone else thinks these forums should be used, as you’ll certainly get such opinions in the replies.
