Welcome to Dear Geek, where I try to answer your questions and share & explain developments in the world of IT without turning you into a nerd.

In fact, if I'm about to say something complicated that you don't really need to understand to get the job done, I'll warn you with a Nerd Alert - feel free to keep out!

If you are at all concerned about any damage you may do, or your business relies on your IT, I encourage you to call out the experts!
