Advice on volunteering

It probably depends on what the role is - if it's on a reserve for example, the application may go to a single individual. If they're on leave (it's the Easter school holidays this & next week remember) it may take a few days to reply. You could try ringing the reserve - they'd doubtless be able to help out. If it's a more centrally advertised role, probably not quite so straightforward to do that of course!
