Justin,
You have joined a really great society. Full of helpful members, activities and resources. NAG (new astronomers group) is well worth joining. 12 months of advice and assistance you just can't get anywhere else.
Sorry to hear you haven't got the response you were expecting, but if I remember back I think mine was a little slow as well. But the society is run by volunteers.
As Mark says, contact the membership secretary and they will sort it all out for you.
Clear skies
Rod
