Welcome to the RBS room booking system! These instructions will help you to find your way around the system and successfully enter appointments.

General information:

Entries in the LSF are not counted as Retina room bookings and are therefore not taken into account.
Please be kind! The use of the Retina computer pools is intended for the entire department. Each lecturer needs time and space for the courses. Please only block as much as you really need so that teaching is not neglected for anyone.
