I would guess that the icon you see is the default icon from the Quickly ubuntu-project template. I am sure that Jono would gladly accept a patch with a new icon. Just drop it into the media directory for the project, and update the desktop file to use it. An svg would be best for that. While you are at it, you might want to create a smaller png to use for window icons, you can set those in Glade.

Thanks for your comment, I have updated the post accordingly

This also means that other projects can use Lernid for their online events too.

So if this software is ment to be used also outside Ubuntu, it shouldn't have Ubuntu symbol in it. Packagers will simply change it, and while Lernid name will be known and recognizable, logo will vary depending on project.And this won't be good.

A graduation hat gets my votes. That is a great symbol for Lernid.
