I really like this plugin! Please Brent, keep it alive. :-)
And to you who would like to use it: Download ver 1.1 here:
I have tested agj 1.1 with:
BP 1.2.3 - does not work
BP 188.8.131.52 - does not work, it looks right in user profile but do not add member to group register
BP 1.2.1 and WPMU 2.9.2 - works!
BP 1.2 and WPMU 184.108.40.206 - works!
BP 1.1.2 and WPMU 2.8.4 - works
