What’s your top social networking site?

G4C has developed G4Cnet.ning.com where members can communicate and share resources.

What’s your favourite iPhone app?

I’m addicted to Who Wants To Be A Millionaire. I can’t (yet) get to the £1m!

What’s your favourite website?

Mapmyrun.com – to map, measure and then be disappointed when I realise I ran less far than I thought!

What are you watching on eBay?

I have never used it but I was close once. Someone was selling a 1985 Manchester United home shirt, which I thought would be a good addition to my wardrobe. My fiancee disagreed.

What’s on your iPod?

Dance music for running, Cafe del Mar for relaxing, and just pure quality like The Smiths.
