Yes, the next day following the listing in Polo. I had acknowledged the project before but not researched it during the inception, takeover, otc and cryptonote-exchange days (in total numbering about 30 days).

So I am one of the most senior of the monerenoj as well, having been involved for 90% of the coin's existence.

Can this information be used to fish other people like me into the coin? I am sure both they and the community benefit
