From your private profile, you can now click on links to explore your current friends, or to find people near to you (within 50 miles).

In the near future, we'll have a way for you to import your contacts from other sources, and invite people directly to the service. 

Since we're in private beta mode, though, you can only befriend current users of the system.

If you joined using a seed packet, though, feel free to share your access code with others.  They can be reused and recycled.
