I was thinking about that, but what is the upper limit - in terms of monthly recurring users - you think for their free version? I guess I am trying to balance the free cost, with the cost of switching 1 month after launch because I have exceeded capacity. Wouldn't it make more sense to just do that from day 1 ? I am just simply thinking out loud, and would love to be corrected where I am wrong.
