tell me please, any person will be able to place applications for sale or addition to the example. Or it will be necessary to have some kind of initial rating.
I do not know what about the rating, but in any case you will need to pay for placing your add-on, I think so. Because you will occupy the resources of the network.
I think it should not work like that, if I want to place a free add-on that really helps people in their development, will I also have to pay for it?
I have not heard anything about it. The developers stated that the payment will go only for the premium features that they will sell. On payment for hosting or something else was not going to speak.
