Some words to our users:

At the moment, the Mutabor team consists of 0 to ½ persons. Besides the fact that Mutabor is offered without fee as opon source software we have a request to all users:

In programming there is an unwritten law: “Each program contains at least on error.” No-one can really check every borderline case (even the obvious my not be tastable). If you find any bugs or errors, please in form us via email to or – even better – using our ticket system. We'd be very grateful for the favour.

If you want to further support our project – recommend it and describe it in blogs and tutorials. Furthermore we need help for the translation, adaption and correction of the documentation, which was originally written in German and is not completely translated yet. Programming is only a small part of a project like Mutabor, which can only thrive from the engagement of users in many areas. In all areas your idias, wishes and offers are very welcome.
