Ability to add post templates for users to use

Hello again,

I am still hosting a writefreely instance myself. For my second request it might be nice to add something like custom templates. I will use writefreely with my community to create a site for book reviews.

I would like to be able to provide my users with a template for certain parts of the review, so they can use them if they like.

For example I fancy to have some general information at the beginning. Like you can see in this screenshot maybe.
