I received a message yesterday (June 20) informing me that my unicorn account would expire soon (June 27) and encouraging me to renew. Just now (June 21), I processed my renewal and discovered that my unicorn account is now valid until June 21, 2019, meaning that I'm essentially paying double for the next few days and losing a few days from the annual cycle.
Now, don't get me wrong. MG.net is wonderful, and the cost of a yearly account is marginal (let alone the cost of a few days). All in all, I'm getting an utterly unique service 24/7 at a price that compares favorably with one decent lunch in Manhattan (where I work). I don't want to make a mountain out of this molehill, and I'm sure that there was no bad intent. I'd just suggest to the webmaster team to amend the system so that purchased renewals begin upon the expiration of the previous period, not before.
Many thanks for all the excellent work you've done to support the global modular synth community.
