I saw that he was online a few times and didn't post anything, so he clearly had access to his account and to the Internet. It takes less than 10 seconds to write "I'm terribly sorry for the delay, I got some issues, will explain on the (date)", especially when you're already logged in, like he was. He didn't do it = he doesn't care.

I'm preparing payments to make up for the missed rounds.
They'll be sent out tomorrow morning.

After that, the campaign will switch from bi-weekly payments to monthly rounds,
but more about that once the payments have been made.

I'll also talk to bitblender about whether, and if how, to transfer the campaign.
