I see the same behaviour for groups that I reported for events in that if you 'Join Group' on the group page, it doesn't refresh to show you the story form which can leave the user confused / unaware they have these new powers after joining....

Could the same fix be applied to Groups as was done for Events to avoid the need for the user to refresh the page?

Thanks!
