So it looks like IBM is giving ConnectED 2015 attendees another shot at receiving the (1) free certification voucher that you could have claimed at the conference if you were lucky (extremely lucky). Some of the people I talked to submitted their information (like me) at the Expertise Zone will a promise that we would receive an email with the voucher within a few days. No such email ever appeared for me; even weeks after the conference. I happened to stumble upon a thread on the ConnectED 2015 conference site where other people were requesting their voucher. I responded as well requesting my free voucher and within a week or two I had received an email with the info.
Then IBM posted a thread giving people the opportunity to respond to another thread requesting a voucher: here
However, today I received an email saying that if you attended the conference you could reply back before Friday March 27th 23:59 GMT to receive a free voucher.
