You can contact us at any time and ask general questions about the system - whether by e-mail or telephone, we are always happy to help you.

However, we may only make changes to the system if we have been instructed to do so by an authorized person. This is to prevent unauthorized persons from receiving sensitive information or from requesting changes that have not been coordinated with us.

Usually, the persons authorized to issue instructions are the system administrators. If you would like to assign new or other authorized persons, we will be happy to send you a form. Please feel free to contact us at any time.


We recommend naming at least two persons authorized to issue instructions. It is better to have three, so that there are always contact persons available for the users of your system and for us during vacation periods or longer absences.
