How do I rename a Shared Photo Stream? The only option in my Shared Photo Stream appears to be "Edit", which lets me add/delete photos. Can I rename the title perhaps online somewhere?
New method for iOS 7, 8, and 9:


Open the Photos app
Make sure you're on the iCloud Photo Sharing screen (tap back as necessary)
Hit Edit (top right)
Tap on album name text from listing
Make your edits
Tap Done to save
