We strongly recommend subscribing to our official email newsletter, which will be the main communication channel besides this website. Like this you won’t miss any important information or updates regarding IBD+ 2025 including the tours and events.

The platform used is the same we use for booking the IBD+ 2025 so that you need an account anyhow – no worries, the account is free of charge.

It might be a good idea to set up your account early rather than doing so at the last minute just in case something goes wrong (not that we expect it, but Murphy's Law applies).

By clicking on the titles or triangles you can expand or collapse the topics one by one; the buttons below do so for all with a single click.

Login

To log in click on the menu entry “Login” on the Booking system web site to open the login page:

Just enter your credentials and off you go... with a click on the Login button.

Usually, your username is your Mensa membership number prefixed by your country code, or in case of a guest account the email address used to register.

If you have problems logging in and resetting the password did not work, please get in touch with Cirsten at office@mensa.de.

Register – Create an Account

If you do not have an account on the online booking system of Mensa in Germany yet, you should create one now.

In order to register visit this page: Registration:

Just fill in your details and make sure you select the checkbox next to “Ich habe die Nutzungsbedingungen gelesen und akzeptiert.” in order to accept our terms of service and conditions (sorry, that part has not yet been translated) and click on register.

As for the gender you can choose between male (“männlich”), female (“weiblich”), diverse (“divers”), or enter what you think is appropriate in the free text field labelled “Freieingabe”.

Please note that by default your account will use your email address as username!

For members of Mensa Germany the account is the country code “049” followed by the membership number.
