Hello! Are there going to be some interaction between the expert and a subscriber? Is there going to be an opportunity to contact the expert directly and to ask him or her some questions? (like a consulting session when a person clarifies what he or she didn't understand out of the expert's analysis and then makes a decision)
As long as they have a verified identity, it is possible to easily contact them in their social accounts. As for anonymous investors, it might be a bit trickier. As of now we do not plan to integrate a messenger system into the platform, but we can do that if the community requires it. Be warned, though, that it is probably going to be a centralized system - it is not possible to send messages in Ethereum directly and conveniently right now.
