In order for us to determine which Linux distributions that are most important to test ATK/VNL on, it would help a lot to know which distributions people out there are using. This will also help us decide which distros to support, in the case we discover some where the programs do not run properly.
Since there are many versions of each distribution, it would be great if you post the more precise distro/version in a comment too.
Thank you for your assistance!
PS: To all the Windows users - we'll make a Windows version poll too, but let's not mix that in with the Linux stuff, ok?
