Inviting a friend to the website is easy once you are already signed up yourself. Simply head to your profile and click on the "Invites" tab under your canvas/avatar:
Then click on the "New Invite" button to open up the invite form:
Fill out the form with their email address, a subject and invite text (like you would any email to that person), and then fill in the captcha box with the correct answer. When ready, hit "Send Invite".
When your friend receives the email, they only have to click on the link inside that has their invite code as part of it. When they complete their account registration, they will automatically be connected (friended) to you through our system.
They can also just visit our site, start creating a new account, and copy/paste in their invite code at the bottom - the same friend connection will be made with you that way.
