How do I create a simple form and use prefixes?

[groovybluedog]

I'm a first timer at this, and frankly the amount of options blew my away that I actually had to leave the computer and make a cup of tea.

I have read around and still do not understand how 99% of it works including prefixes.

So the question: how do I (keep it basic please ) create a simple form when a user creates a thread in a specific forum, and can I remove the actual thread message box so it's only the title and the fields?

Then of course, what's the easiest way to use the prefixes?

Thanks
