I have been using Linux for 2 years now. I started with Ubuntu 13.04 and played with a few Distributions as well. So I have experience with the following Distributions:

• Ubuntu 13.04 - Ubuntu 15.04
• Fedora 19 - Fedora 21
• Ubuntu Gnome 13.10 - 14.10
• Deepin 2014 - Deepin 2014.2
• Mint 15 - Mint 15
• Raspbian

I'm still a little new to Linux, and not the best but have had messed up my Distribution several times just to fix it and gain more knowledge about linux.
