How can I find out who my friends have added and which communities they’ve joined?
You can follow your friends’ activity using the Updates tab (vk.com/feed?section=updates). When you open the tab, you’ll see a block of filters that will allow you to choose the kind of activities you want to see.
It’s important to know that privacy settings (vk.com/settings?act=privacy) apply to the Updates section as well. A page’s owner can edit the Which of my updates appear in my friends' news setting, which limits what appears in other users’ updates.
