Just bumping up this thread in case there are FT'ers who dont know about this (I didnt know about this for a long time !!) and new members.

Looks like its still on but I havent sent any referral links to anyone yet.

You have to log on to your skywards account first before clicking the refer a friend link

Here are the T&C 's

You can refer up to 10 family members, friends or colleagues who are not already Emirates Skywards or Family Bonus members.
Nominees must be over the age of 16.
For you to receive the promotion offer, your nominees must join Emirates Skywards within the eligible promotion period and take their first flight within six months of becoming a member.
Applications received after 24:00 hours on the last day of a promotion cannot be considered for that promotion.
On the general promotion, you earn 1,500 Skywards Miles if your nominee joins Emirates Skywards and flies in Economy Class, 2,500 Skywards Miles if they fly Business Class and 4,000 Skywards Miles if they fly First Class.
