As I previously wrote, I went to Athens to attend the FOSSCOMM annual conference.
I applied to present something related to openSUSE (I was at the booth) and also to ownCloud.
The audience was aproximately 20 people. Actually it was the first presentation of the day, right after keynote (at the other room). The good thing was that more came at the booth and they were asking about Tumbleweed and Leap.
We had limited amount of swag to give away.
Here you can find the presentation file. Feel free to use it.
