Hoping you change your mind last minute or find someone to take it over. It has been too many years of good stuff and frankly, just too many people rely on your site to simply close it.
I don't mean to sound preachy or try to make you feel,bad, and in fact the opposite. You have built something that now extends well beyond yourselves and while, indeed, you may own it on paper and have every legal right to close it, at this point it belongs to the world and should remain active however possible. That is a credit to your good works.
Asking you to reconsider and let your built legacy continue into the future, in whatever form that requires.
And of course, the very best of luck to both of you. Again, thank you.
