Previewing Posts before Publishing

Heya!

I'm about to create a thread that contains A LOT of work and I was wondering if there is a way to preview a post before publishing. I may be blind but I don't think I see any buttons or anything...

I plan on using templates or codes (not quite sure what the accurate term is) for the first time and I'd rather not have people see a piece of work that looks like a corrupted word document.

Specifically, I plan to be using Subzero's template in this forum post:
https://www.smitefire.com/smite/forum/god-item-ideas/a-note-to-all-members-of-the-smite-god-making-community-2740
And I'd like to use his template, but I don't know how to implement it into the post itself and make it look all pretty.

Thanks!

Edit: Oh yeah! Is there any way I can play around with a post? Such as: Type whatever I want and practice coding and that nobody will be able to see the post except for forum moderators? Thanks again.

I would recommend creating a guide that you never intend to publish, using it for things such as this. I have one of my own, as it makes it very easy to simply save + view and see how it looks. There is a slight difference in the width of guides and posts that might affect presentation, but I don't think it'll be too bad.
