Hi Fady,
Thanks for contacting us. The 3 communications that went out recently were surveys sent to a specific subset of our community, and some Kickstarter updates.
If you weren't a KS backer, you'd not be notified of these, and likewise, if you weren't in the subset of users we recently emailed as part of a survey, you wouldn't have received those either.
So in the end, you are registered, but none of the recent communications were intended for you.
Is there something specific you know you missed that you feel you should have received?
