ok - there was a problem with the mbin queues on fedia - I think that may have caused the problem with registrations. Can you give it another shot? Also, if that doesn’t work for whatever reason, please shoot me an email to jerry@infosec.exchange so I can debug the issue.
It really is great and we’re very lucky to have the mbin team that we do. I sincerely appreciate them, as should everyone on fedia.io and the other mbin instances.
