Contribution and Lizensing
All partners and members of the Open Source Community are welcome to contribute actively to the development of UCS and integrated Open Source components. To integrate changes and extensions in UCS and other products of Univention, a contribution agreement is needed that allows Univention to distribute Univention Software including contributed changes from third persons under the AGPL and other license terms. Please download the appropriate contribution agreement, sign it and send it back to Univention.
We are looking forward to your contribution. You may send them to firstname.lastname@example.org or upload them into our bug tracking system.
More information about the Univention Open Source philosophy can be found at the Univention Website.
