Dolphin has a lot of ways for your user interactions. They can post articles, blog, polls, upload videos, music, photos and much more. I run a community site for our small town and we use it for our residents to post articles of interest, promote events and groups, create polls and about everything else Dolphin lets us do. The groups can be especially useful as you can also create articles there. The Forums will give everyone the ability to post information as well. Pretty much ANYTHING our see more members want to do, they can. It's a great interactive program and it will do so much more for you than your existing WordPress site. Look for some of the advanced mods for Articles, Groups, Events and Polls as well. They add a lot of features and interactivity to the base system.
