I found a related (old)post here

I'm currently using usp pro as a frontend.

I'm creating a free pet memorial site, and want the user to just fill out the form, (NO ACCOUNT REQUIRED),and the post is created, which works fine without any issues. BUT there isn't any options to preview the post, only submit it.

I really want to give the users many design options, but a preview function are required, but I'm not an expert in php, and certainly not in WordPress.

Anybody that knows anything about this?
