I have a multisite intalation and I installed the prosites

Hi,

I have a multisite intalation and I installed the prosites plugin. But, when the user does not pay the month I noted that he receives the email informing about the expiration date but he can acess the site normally, even after the site expires.

I would like to block the acess to the subsite expired or to show a message about the expiration in the content site.

Is there any way to configure it in the prosites? How to do it?

Have a nice day.
Thanks.
