I have just finished writing my first Wordpress plugin - a widget to display a status update via Ping.fm:

Ping.fm is a simple service that makes updating your social networks a snap. You can use AIM, GTalk, iGoogle, Windows Live Messenger, Yahoo! Messenger, WAP, iPhone/iPod Touch, SMS or E-mail to let Ping.fm relay your message to a multitude of social networking sites. This plugin lets you use Ping.fm to add your status to your Wordpress Blog’s sidebar via Ping.fm’s “Custom URL” integration.

== Installation ==

* Extract archive
* Upload entire ‘pingfm_status’ directory to ‘wordpress/wp-content/plugins’
— do not remove files from directory, upload the directory with all files in it
* At http://ping.fm create a Custom URL to update the following address:
http://url_to_your_wordpress_installation/wp-content/plugins/pingfm_status/pingfm_post.php
* Enable the plugin in your Wordpress admin section
* Add pingfm widget to your sidebar, set the Title

== Notes ==

If you notice that the timezone is incorrect on the timestamps that appear in your updates,
you can change it in ‘/wp-content/plugins/pingfm_status/pingfm_post.php’. I have included
some notes in that file.

Here is a link to the plugin in the Wordpress Plugin Directory.
