Is there a beginner's guide?

[maributa]

I'm looking for a topic for forum beginners
I just want to try different ways to use it.

Where is the best place to ask very basic questions?

I have read the rules and guides 

I wish there was a place to practice before posting in the correct place, but I can't find it.
I would like to practice pasting images...

I'm scared because once I post a topic, I can't delete it myself (Isn't that right? Can I delete a post?)
I didn't know where to write this post either.

Someone please give me some advice
