Make referrals count
Make your referral link really count.
After signing into aitp.org, on the left hand side of the page click the "Refer a Friend" link.
Your Referral Direct Link is displayed and can be copied to anywhere HTML links will work.
If your link does not contain a public key, click the "get new public key" link. For example, your public key will be after the ref= part of the link and appear similiar to the example shown below.
Now use that referral link on your blog and in tweets and emails to other technology folks.
