[edit] Introduction

I very much welcome comments on any of my contributions (naming, format, style, contents, usefulness etc etc) - post a message at User_talk:Gandalf61.

As for myself ... I am British so I enjoy :

The outstanding comedy of Monty Python and Fawlty Towers
The animation of Nick Park
Singing along with Flanders & Swann
Eating Marmite on toast
Drinking dandelion and burdock and warm beer (but not both at the same time)
... and playing Diplomacy, Risk and, of course, Mornington Crescent

[edit] Motto of the day

Today's motto...

It's 'Pedia. Wikipedia.
