This plugin allows you to assign tags to BuddyPress groups in order to categorize them. You can then show a clickable tag cloud above the group 
listings or as a widget. BuddyPress 1.9 friendly.
New to version 2.0. You can show group activity stream based on tag. For example, if you have ten groups tagged ‘sports’ you can show a combined activity feed for just those groups. It’s powerful stuff for larger sites with lots of conversations. using the gtags_group_activity() function you can even find the activity of groups that share two tags, or you can show activity for two tags added together.
Group Tag activity shortcode example: [group_tag_activity tag=Love show=10]
There is a group tag activity widget
There is an admin where you can turn off and on different aspects of the group tags as well as customize the tag cloud.
