Wordpress uses several plugins. I often get e-mail by people wondering which plugins I use the most in my websites, so I hope this list can be useful:

XML Sitemap Generator

Wp-ecommerce
Cforms II
WassUp
Google Analytics
WP-polls
WP-DownloadManager
All in one SEO pack


This site runs on the new Wordpress 2.8.6 and It seems like every plugin runs smooth. All these Wordpress plugins are easy to use and very useful if you are selling stuff on your website.

THere are a few more good ones for autoposting stuff on your website. Drop me a comment and I can guide you.
