That's a very small step forward, but I'm happy to see the number of people being interested in my project slowly growing. My project is a windows desktop application which I guess is less legitimate to ask for an email than a SAAS or webapp . We all think twice before leaving our email in some new website, with no historical background.
Until now I only used IH and reddit as communication channels.
Anyway, I really hope when the beta version will be available more people will be interested !
