A fairly complex custom Wordpress template with quite a few unique pages that I built from scratch. I used the bbPress forum plugin (along with the bbPress Threaded Replies plugin) to implement a forum which required some customization. I also implemented a member's section that used the Role Scoper plugin to limit access to specific pages. They needed some modules and pages to be associated with others, I used the Custom Post Types Relationships plugin to accomplish that. The TablePress plugin was used to create timetables displayed for the yearly conferences the organization does. Finally, I used the WP Approve User and WP-SpamShield plugins to control the process of approving users signing up for accounts and to control spam from the forms I created for the website.
