Site Tour - Friends
Inviting members to be friends lets you keep track of what they're doing on the site (click for larger image).You can invite other members on livingOUTthere.com to be a friend. And you can also invite people who are not yet members of www.livingOUTthere.com to be members, which, when they do, will automatically be added to your friends list. 
Friend Activity is listed on the home page if you've selected that option in your account settings (click for larger image). If you've selected the option in your account settings, you'll see their activities on the front / home page, right below the gallery of new members. So you'll see if your friends have posted to the forums, written a new blog entry, put an event in the calendar, or updated their profile. It's a nice way to keep track of what they're doing, and stay in touch. You'll also know when they post something that you might like to comment on.
