So far, this book has introduced the basic concepts and the most commonly used features of ExpressionEngine. Many of the same basic skills have been used time and again such as setting up custom fields and categories, creating a new channel, posting entries to the channel, and building templates with HTML/CSS and ExpressionEngine tags.
ExpressionEngine comes bundled with many other modules that may or may not be useful, given your website. The modules range from the simple to the complex — the simplest create additional tags that you can use in your templates, while the most complex include their own configuration pages and library of tags.
This chapter looks at some of the offerings, including:
The Search module
The Mailing List module
The Email module (create a contact form or a tell-a-friend form)
The Moblog module (submit new channel entries via e-mail)
The Wiki module
