Is the plan for this project to be invite-only forever?  Or just for a limited period of time? 

I think we are all familiar with famous growth stories based on an invite-only model.  (Facebook, GMail, Pinterest, Spotify)

But, I think in all of the above cases, the product eventually CAME OUT of this invite-only stage and became publicly available. 

I'm not saying this is needed for Merit to be successful, but I'd like to understand if there is some plan for this.
