What sort of revenue can we expect?

[Arcturus]

For those of you who have an active marketplace and would be kind enough to answer, what sort of revenue are you getting now? Say you're using a subscription plan at $5/month, how many paid users do you have on subscription and how much commission are you getting on average? Perhaps you'd also like to share how active your users are (do they generally stay active for months at a time or do new users join every month)? What are your techniques to keep them active?
