I can see that the site has had some changes in the last few days.
I have been exploring the changes and plan to have some information in the forum as soon as I have something to share.
The 'Friends,' it appears, is so that you can reach out in friendship to someone. I think that there is going to be more to it shortly. As I said, I am still looking and poking around, but there is 'groups' and that might be related to 'friends.'
The Net is full of sites where you can 'connect' with someone as a 'friend.' Flickr is one of them. If you click on the "Contact" in the right corner of this thread, you will see 'add pat71896 as a friend.' That is how they selected you.
So far, I am just looking at the avatars which are showing up in my profile. These are the people with whom I have had some contact, I think it is cool!
