Hi Sarah,
We had some problems with the webex files which were recorded during the conferences. The files seem corrupted. I tried several approaches to recover with the help of Webex support. Unfortunately, no solutions have permit to bring back to life the videos for now. I tried some linux tools but unfortunately the format of webex is not open. I hope I would be able to recovered them but, until that time, I will suggest to everyone on the mailing list to post there conference here.
As mention by Hannes, I would find it particularly interesting the idea to link
geomorphometry.org and
open-geomorphometry.org. (or post at least a link on geomorphometry), because the google groups has not the same visibility. That is not very good if we want to produce a tool useful, usable and used.
