First let me say thanks to Joomlapolis for picking up the development of this valuable tool. My site is in development, so I can test whatever you need. I'm a techy guy, so I'm good at giving feedback.
I have the component installed on J 1.5.1 and CB 1.2.1. The installation went fine, although I do think the documentation could use a lot of work. (More on that in another post.)
Here's my bug. When someone creates a group, I receive an admin email telling me there is a new group that needs approval, the links are missing the base part of the URL.
Here's an example:
A new group has been created in category "Backup Hardware"!
Name: SEPATON
Description:
Link: index.php?option=com_groupjive&action=gj.core.groups.showgroup&groupid=21&Itemid=15
Instant activate (!): administrator/index2.php?option=com_groupjive&task=publishgroup&cid=21
