The Best Classified Plugin
Great solution if you want to set up a classified ad section on your site. No login by users is required. There are paid add-on modules, but the free version is totally usable. I purchased the add-on module that lets you use custom fields.
See an example in action on the Pacific Crossroads Church website.
The Best Directory Plugin
Great for setting up a user-managed business directory or even a Yelp! clone!
Two Great Membership Plugins
Great for setting up a membership site where you sell restricted content. Allows “child” accounts that are linked to the parent account.
This is a very popular membership plugin that has tons of features out of the box, plus paid modules. Pretty flexible with some learning curve.
