We forgot to discuss the licensing of the logo. It is your work and you get to decide. The goal is to distribute the logo in every release of Enough which is a Free Software released under the AGPL license. It would be fine if you decide to publish the logo under the same license (i.e. AGPL), of course. But it would also be fine if you decide to publish the logo under a compatible license.
Please let us know what is your preference.
For the record: the deliverable permalink with the license is in the artwork repository
