Hi!
I'd like to know what is quota?
Have I to buy some quota to make new websites with JMS?
Thanks to explain to me with more details...

Quota is an option available for the front-end website creation that is required when you want to customize the website creation or when you want to sell the website creation from the front-end.
Otherwise, when you use the default JMS website creation from the front-end, this is free.

To buy quota, this is available from the "Setting" menu in JMS.
The price depends on your actual quota.
You buy quantify package and several quantity package are available.

The quota is available for several master website and not to the specific JMS installation.
Therefore you can have several masters that will share the same quota.

To have an idea of the prices:
It start at 15 EUR for a package of 10 websites when you current quota is null;
600 EUR for a package of 1000 Websites when your current quota is null;
to arrive at 300 EUR for a package of 1000 Websites when your current quota is >= 1000 websites.

As you can see, the price for each website is not very expensive.
