This looks really nice and something I'd be interested in, but I'm wondering how you arrived at the pricing model. $49 for 100 conversations seems steep to me and not something I could afford for smaller projects.<p>So if I have 100 users who each have one conversation, is that considered 100 conversations? If I have two users talking with each other, is that one conversation? I looked through the FAQ but can't quite understand the pricing model.<p>Also, when I click on "We can't afford TalkJS" in your FAQ, it expands the answer for the question.
