Editorial

Welcome to Issue 4,

This month the team are very proud to annouce that for the first time  The MagPi has been created entirely using Raspberry Pi computers.

As promised, we bring you our interview with Eben & Liz from the Raspberry Pi Foundation.

We have some new articles as well as our popular series covering hardware projects, programming and other general operating tips.

We have received a good response to our request for volunteers.  There are now a few new additions to the team, however we are still looking for more help, so please do come forth!
