Preview Post feature?

In most other online forums in which I participate, one has the ability to preview one's post before submitting it. Perhaps that feature exists on this site and I just don't know how to find it. If that's so, I hope someone will point me in the right direction. If not, I hope the site admins will consider adding that feature. Thanks.

you have the ability to edit it in the first hour after posting, so in a way, you have exactly what you are asking for
