i think that once a month it would be enough, and in the absence of news, they(team) could say we are actively working on the project and we will keep you informed as soon as there will be anything relevant...
Some kind of clear information channel need to be established. I see few tweets once in a while but that clearly is not enough. The CEO i think is active in telegram, did anything happen there?
CEO is semi-active there, he posts some news from time to time, but dont reads actively and dont answers to every question.
Most postings there are some research results from the medical sector, not how eHealth is developing.
