My favorite co-operative hosting provider Ouvaton will soon be using Hostflow to manage its (new) platform, allow its users to manage their services, and invoice for usage. It’s looking pretty good already, as it includes the Sympa mailing list system.
We’ll have to adapt to many of the new platform’s details, we’re not happy about them all, but the improved and new features are overwhelmingly positive. Soon a beta release, I hope that the users’ response will be positive as well!!
