Contribute FOSS4G 2009 Videos to tib.eu

We have a request (from Volker as coordinator of FOSS4G 2009 Presentations). The FOSS4G 2009 website states all material is available under CC-BY-SA. This statement is insufficient for https://tib.eu/ portal which would like license agreement.

Would the board sign the license agreement for talk where the
authors/their organization have confirmed via email that they license their talk under CC-BY-SA?

Additional details:

• The FOSS4G 2009 website states:

The conference material is available to all under the terms of the Creative Commons Attribution-Share Alike license

• An email was sent to presenters:

Confirm that your presentation may be made available, preferably
via the Creative Commmons Attribution-Share Alike license:
http://creativecommons.org/licenses/by-sa/2.5/ Do this by sending
an email to foss4g2009 at lists.osgeo.org stating:
>
I, "first name" "last name" confirm that my presentation titled
"title", and presented during the FOSS4G 2009 is available
to all under the terms of the Creative Commmons Attribution-Share
Alike license: http://creativecommons.org/licenses/by-sa/2.5/

Producing 25 responses.

Volker has offered to go over the old thread and see which confirmation we already have. And send out email to the people we have a video from.
