@Gargron That vacation is well deserved, seriously!
I knew you were taking a short vacation, but you are still active on Github, so I thought you were back or had everything to you disposal on your vacation. So that confuses people, including me. So if you are not able to renew that certificate when you are away, please notify people, so they will know it will be fixed when you are back from your vacation.
Have a nice trip back home.
