Are there other mayor ISKCON forums?

This one, and most others, are so little active... Replies can take several days. I wish to discuss my faith in depth... :(

Not to my knowledge, if you

Not to my knowledge, if you mean large, active forums populated by senior devotees. Mostly you find average quality forums with devotees or sympathizers in peer-style talks, e.g. http://www.iskcondesiretree.net/forum
Some gurus have websites and you can ask them by email. But best to ask personally in the temple.
