I mentioned this in a seperate blog, but I'm not sure Boonex has seen it yet, and its a bug that is still in 6.1.1. Its been tested and confirmed by severa of us, with fresh installs.

You cannot have more than one join page. As soon as you set any fields to additional pages in the join process you run in to problems.
