These are great feedback folks and exactly the team need in working out a sustainable solution to all.
I try not to talk about the commerical in great length here as I don't think our vb.org moderators will like it. But I can share with you here that the business model is from the pilot forums owner input - that they want the app is free so their members can access to increase user stickiness to the forum, they see this is a add-on to keep the user royal.
Please continue the commerical discussion at
