Signup link is missing, and does this support only BuddyPress?

Ok I followed the instructions in the PDF but still have some problems/errors:

1) I am running a BuddyPress site without any multisite capabilities. It's just a WP/BP combo that has a community, forums, and groups. Is this app built for something like this?

2) When I run in the iOS Simulator, it appears a "Sign Up" link is missing. It only has a the 3 textfields for username/password/site address(url). Did I miss this some place?

I have some more questions, but they may be solved based on the solutions for the above 2 questions. :slight_smile:
