12.04 has served me well and very soon the new LTS arrives. I am not brave enough for the beta release but it has been said it is far more quicker than 13.10. The sad news is that Mir (replacement for X11) will be not standard in Trusty but it will be in the repos if you wish to give it a spin. I decided to further the cause of ubuntu by introducing a set of videos from my You Tube friend. "jthelinuxguy" has given his blessing to share these.
Linux for Beginners is a great primer to the command line interface. There is other subjects are covered that might be just as interesting. Enough for now and my welcome to our new members.
