I work in a public library where Adobe ID's and Adobe Digital Editions is used to borrow our digital material. We have got a lot of devices, ebook readers, tablets and computers that we use to instruct our visitors regarding how to download our books. The limit of six authorisations per account is a big problem since we then would need multiple accounts for our devices, we also would have to remember which device is connected to which ID. We would like to register an account where the limit of devices is set higher than six so we can use the same ID for all of our instructional devices. How can we accomplish this?
