We had a very prominent footer showing how to get in contact with the
local instance people but most users need to get in contact with the
enterprise they are buying from. So removing all those details and
replacing them by a simple "powered by" line will hopefully direct
attention to the shop's contact details.
A bug introduced in a9c37c162e caused the
creation of confirmation emails for shops to fail. The email template
got fixed now and the email address from the database is displayed if
present.
