Users creating events in groups and auto approving all events submitted to the site

I am having issues where I have allowed users to create events in groups, or events in general on the website. However, every time an event is created, I have to approve each and every single event. In addition, nobody in a group can create an event from within that group. I thought I had everything figured out in the ACP, but even still, Users are unable to create events in a group, and I still have to approve all events submitted to the website. Is there some way to override this and allow users to create events from within a group and also to make it so that I do not have to approve every single event sent to the the site?
