New Social Features - Google Friend Connect
In addition to the private messages, Friend Connect also added "Interests" and "Newsletters".
Interests can be filled out by you, so you can see what you have in common with other users of the site. For example; Eric has man crush on Dana White and notices that Whitey lists MMA in his interests. Eric could then send Whitey a message asking him about which UFC fighter has the best calves. Right now I only have location and gender enabled, but please leave your suggestions in the comments.
The Newsletter feature is just that, a newsletter. It is opt in only (I think) and lets me or another site administrator send out a newsletter to all the people who subscribe to it. I put the newsletter subscription gadget down at the bottom of the page... although I have not determined what if any content I would put into a newsletter for this site. If I do make one, I will assure you that it will make your children cry (in a good way).
All the new this stuff is easily accessed by clicking on your settings after you login to Dolphin Free.
