Sadly, Tony seems to be objecting to other people sharing this content:
The wiki is back and in the process of being moved permanently to a new home. Tony says on the home page:
It is currently in the process of moving to a new location. Any changes you make between now and then may be lost during the move. Details will be made available here when this is ready, and presumably also on the new CdbiMailingList.
This site was unavailable for a few days in an attempt to prevent it being replicated it elsewhere. Sorry about that. Hopefully we can get on now with a proper handover.
