Hi Benny, I'm glad you are liking MoI!

But I'm sorry I don't have any plans to make a month to month subscription option. The main reason for that is that I like to keep things involving billing to be as simple as possible and dealing with monthly recurring billing would vastly increase the number of transactions and there would be a corresponding increase in the amount of time spent to support and administer that.

Since I'm just one person doing both development and support as well it's pretty important for me to keep the amount of effort required for administration and support to be low.

Sorry that doesn't fit with what you need.

Thanks, - Michael
