As for the actions, here is what I think. Even in the so called 'survival phase' when many coins are born and die, ZEIT needs to have something that will mark its presence, and would distinguish it from other dying coins. Something, that will help the crypto SETI enthusiasts to have ZEIT on their radars (please excuse the old-fashioned astronomy analogy). A complete silence is not a best way of advertising a product, if you ask me. My suggestion is to have some form of 'keepalive' message to the community (with a fixed frequency, say once or twice a month), preferably not only in this forum, but to a broader scope (aka social media) to reach as many new users as possible. What could be in such message? To start with, similar things to what we post in this forum, e.g., advertisement of the update of blockchain snapshot, review of the global ZEIT volume in the last month, etc. It doesn't need to big thing, but something to show the activity of community. I believe this could be done without waiting till the 15% PoS rate drops.
OK,
You're in charge of the keep alive messages.

No problem. I'll send you a pm to discuss the details and how to proceed.
