With Yahoo! 360°, other users (or just your friends and family) can see what groups you’re in. Who knows? They could be inspired and want to join, too. Or, if you’re not sure you want to display your groups, no problem — you control who gets to see this information.
To share the groups you belong to:
Note: Only "public groups" (where anyone can join the group without approval) can currently be displayed. And groups in the adult categories (such as "Romance & Relationships > Adult" or other category with the word "adult" in it) won’t be displayed.
