I've used your plugin with great results!
Wondered if you can extend the plugin to work with BuddyPress Groups.
Basically, I'd like to be able to create a separate BuddyPress group for each WP category. The BuddyPress Group Organizer and BuddyPress Group Hierarchy plugins allow for nested groups and extending your plugin would allow one to quickly import the nested groups the same way you have it importing categories.
Ideally, someone will write a plugin that will connect WP categories to BP groups so that they are tied together and can be added/edited/deleted in one shot but until then, your plugin could allow for quickly creating hierarchical groups.
