It does mean just that in this situation. Volunteers generally are unable to commit to paid work, so what if they can do something they enjoy? Stop trying to find problems when there isn't one. I'm sure if anyone doing voluntary hours felt 'exploited' they'd volunteer elsewhere?
Exactly.
People are talking utter rot and making an issue out of nothing
No-one is being forced to do anything they don't want to do, they are doing it willingly and happily for free, and people are talking utter nonsense saying Mumsnet should be paying them.
And still none of these whiny naysayers are answering the question I have asked....at least twice......
DO YOU KNOW WHAT A VOLUNTEER IS?
Do you???????????
Obviously not! 
As I said, some people are beyond help. No matter how many times we show them and tell them they are wrong, they will still keep banging on as if they are right.
As I said, report mumsnet to trading standards, see how far you get with your petty drivel about mumsnet 'exploiting' people.
