It's all about the group

Group administrators are the designers of the group. As an administrator, you create your group(s) and add the features "Messages", "Events", "Files", "Requests" etc. as required.

This is very simple - and can also be adapted later.

Subgroups - structure, overview and order

Within groups, any number of further groups can be created. Regardless if you need the same or different members and depending on the purpose: person or topic related.

Group administrators create these subgroups (groups-in-groups), choose appropriate group names and assign members. Subgroups can be rearranged at any time. mantau supports constantly changing organisations with many projects.

This way you can chat topic related and clearly assigned. You can store files similar to the way you are used to from the conventional file manager.

usual formal requirements of individual members, e.g. registration forms. 

The results are presented clearly on request, e.g. the ideal date for everyone - or transmitted confidentially, e.g. personal data.
