Users complained lack of preview, how to fix?
They just need to edit post a lot.

There’s no such function in bbPress at the moment, nor do I know of any plugins that can do this. You could write a small javascript snippet to paste it in a preview border.

I have no skills with writing javascripts or any scripts. Is this possible to buy somewhere, some custom work on bbPress to make live preview?
