Perhaps the time has come for there to be just one "Umbrella" Services oriented charity?
The RBL has been in existence the longest and could provide much of the admin etc for these "specialised" areas to ensure the best use is made for every pound donated, not lost in each charity with their own admin, advertising, organising and premises to run before anything left goes to the actual cause?
Not knocking the need for the money to help the wounded, injured and affected regain as much normality, just the duplication of effort...
