If you recently received an email like this:
It’s legit. The warning looks scarier than it actually is - just like any http sites without the “s” (https), if you are on a PUBLIC network, be careful when registering new accounts. If you are at home, it’s no worries. 99.999% of the time you’re fine, but yea we will add the “s” to https soon!
We added SSL (https) to all of our sites so far except the forum. The forum is next – but we we plan to add it in a couple weeks (after Alpha). As long as you’re on a private network, there’s no concern. It’s the same for any http (not https) site.
We’ll add https ASAP after alpha is released 
don’t worry!
