Haha, welcome to EC. To send someone a friend request, you can go to their profile and on the right-side click "Befriend <name>", and it will give you an option to send them a friend request. If you're viewing a thread, you can click their username and a menu will pop up, the bottom option being "Add <name> to your contacts." Those are the two most common ways that I add people. Hope you enjoy it here. See you around the forums. If you have any other questions about the mechanics of the site, my profile's wall is always open to you, or you can make a thread in Empty Closets Help & Feedback.
welcome... buddy, trust me, forums are not easy to figure things out, I gotta admit it, I find new things on the forum every day o.o
