Contact details for GSOC'15 mentor

Dear candidates,

as the question has been asked to me several times, the fastest way to
contact me if you have a quick question to ask that needs an immediate
answer is with Google Hangout (formely Google Chat). My contact detail is
my email address: [email protected]

I have it on my screen during the day and can answer faster than by email,
that I usually read at night when I'm back home.

I'm based in London, UK for the time zone.

Best regards,
David
