Going by what I have observed in the forums to date, I think that CSers have been helpful in giving pointers to budding photographers for their first wedding shoot. And I believe this help can also be extended by providing checklists as a sticky for the hidden costs involved in a wedding shoot, for example. Better still, the experienced pros can organise workshops for budding photographers on how to take on wedding assignments and how to price appropriately for them.
update: shinken's new thread is a v good read for all aspiring wedding/commercial photographers. should be made a sticky.
