So I've installed the friends plugin. It's great and I think there are some easy wins to make it even better.
1. When you add someone as a friend, automatically redirect back to the blog that you were on. There is no need to go into WP-admin. It would be cool if there was a little message that said "Friend Request Sent" or something back on your new friend's blog (in the sidebar)
2. Display the user name, not the blog name as the friend â€” I'm not friends with blog, I'm friends with people.
Any more out there? These are my big 2 for now. I've also mentioned elsewhere that tying in friends and invite would be really nice...if that hasn't been done already.
