Pros: Saves time when listing multiple items. Helps ensure contributors add correct information. Speeds up posting of new content.

Cons: Taxonomies need to be scrubbed from the database after they're deleted. Doesn't work with several custom eCommerce themes. Premium version doesn't offer enough to justify the upgrade fee.

Pros: Create a file-sharing directory organized by categories. Option to preview files before downloading. Create income by charging for uploads and downloads. Integrates with other plugins.

Cons: Security features are only available in premium.
