I maintain a bit more than a handfull of WordPress plugins. On this website, you will not find much, besides the Gwolle Guestbook Add-On that you can buy.
For the free/gratis plugins, check my profile on wordpress.org.
WordPress is the most used and most userfriendly CMS of the moment. It assumes that layout and content are separate. The layout is made by the designer and developer. The content is made and maintained by you, the editor and owner.
