BlogSpeak will be back up by this weekend, maybe. Tino has set me up with hosting, however I don't know if it will work the way I need it to. HaloScan has offered to pick up the hosting, and transfer everyone's comments to their system.
Commenting will be back up as soon as BlogSpeak is. It's an excellent service and I'd prefer to stay with it. Thanks to the people who emailed me about the missing comments.
