hi,
Just an update on the ongoing demo farm revolution. I was under the impression that the current aws t2.medium instance was going to limit us to 10 demos(note each demo uses a docker container and the t2.medium instance has just 4GB of memory). However, @robert.down suggested that to decrease the overhead, it would make sense to serve multiple demos from each docker container. So, have added the ability to have 10 subdemos per docker and did this to 1 docker to see how things work, which seems to be working well. This basically means we are serving 20 demos now and could likely serve many more; of course this is because the traffic is almost all to one demo (the official demo linked from main website), and if they all got heavy use they may run into some issues 
I made all the new demos Up For Grabs demos, which we now have 12 of

This mechanism will also prove helpful in the plan to support education(since could basically make a stream of demos that deal with a set of instructions sets with very minimal overhead):
@visolveemr , btw, still working on the alpine email issue.
