BP Social Theme - quesitons on Community Tab

Working with BP Social Theme on WMPU/Buddypress. A few questions/issues...

1/ When I'm viewing the front end, I'm not (as an administrator) able to create any groups. How can I create a group as a user with this theme?

2. When clicking on Community > Forums, the page just refreshes and doesn't actually go to /forums.

3. Is there an output of the "sign up page" somewhere I can edit? Can that be transferred to an actual page in the WP pages dashboard?

Thanks in advance!
