I've written a new plugin for Wordpress that will allow you to display your 25 latest forrst (public) posts using the forrst API.

Usage is very simple enter your Forrst username, on the plugin options page under settings then put [wp_forrst_posts] on any page you want your posts to be displayed.

You can download this plugin from the Wordpress plugin repository at http://wordpress.org/extend/plugins/wp-forrst-posts/ or get it directly from your Wordpress admin by going to Plugins then Add New and search for WP Forrst Posts

UPDATE

This plugin is now available on Github https://github.com/stefanbc/WP-Forrst-Posts thanks to Stefan Cosma for starting the fork.
