Referral code?

I logged into the welcome page the other day, as a friend of mine had recently checked out the site. There’s mention of a special referral code. What is this? Can I give it to friends who are checking out LingQ for the first time?

This is a capability for when we have promotions. When we do you will be able to use this referral code. Right now we do not have any promotional program. Stay tuned.
