We just set up our first Acquia Drupal site. Its for a client, I was assuming / hoping there would be some kind of reseller / multi user login system. Where by i could give out user login details to the client, so they can monitor the site, heartbeats etc, but without giving them access to all the sites we (hope in the future) have set up with Acquia.
Additionally, a system were more than one admin user (e.g. other techincal staff) could share access to the same account/selection of sites.
