Telco giant BT's remote monitoring business BT Redcare today issued a challenge to all online users to raise money for Comic Relief's Red Nose Day.

And to start you off, here's a hint: the ones on the home page don't count. If you find all six, BT will donate £1 to Comic Relief.

To take part, email the URLs of the pages where the red noses are concealed to [email protected]
