We have all seen or contributed to top user-generated content communities in the past. If you would like to start your own, you need to find a way to accept submissions from your visitors. Snax for WordPress can help. It is a front-end uploader that lets your visitors share content with you. Your visitors will be able to submit content to published lists.
Snax also lets your visitors open lists. They can include images and videos from Instagram, YouTube, or Twitter. The community gets to upvote or downvote every submitted item. A widget for displaying the latest lists is available. Snax supports 20+ networks. It integrates with BuddyPress.
Snax supports open and ranked lists. It is expected to work with a wide variety of themes. This is a commercial plugin by an Elite Author.
