Hi, Am currently using DNN v6.2.0(community edition). I used the social groups module but I have some challenges with this module:

1. how can other members sign up to a group other than the admininstrator?
2. when deleting a post, there is no confirmation message as to whether you are sure you want to delete or not.
      I also used the FAQ's module, but after populating the questions and answers, it doen't open upon clicking on it, except I want to edit the questions and answers. why is this so?
