Works fine on it's own but this really doesn't add any functionality to the current JomSocial 2.x.x and it's something you have to facilitate separately even though it says it integrates. You have to buy templates or customize them yourself. Adding events is more involved and complicated for front end users than the built in functionality of JomSocial. You can't control user groups easily and moderation is so-so at best. Blah.
