Good on them Martin.
From the site...
"The "Don't Just Walk Past - Tell Us" campaign gives people the option of calling a 24-hour helpline number 0800 567 76 99 or completing a form on the charity's website
http://www.porchlight.org.uk/tellus. You will be asked some simple questions about the person you have seen so that the specialist rough sleeper team can easily locate and identify them."
Ignorance is bliss, bliss is happiness, I am happy...to draw your attention to the possible connectivity in the foregoing.
