How valuable can a forum with 15,000 companies (most of which are bad) spamming their services ever offer any real value? If you're lucky to have a good group you might find value, otherwise it's going to be pointless.
I'd encourage seeking out other, smaller founder mastermind groups - you'll get much more value there.
