I am looking to set up my site where a user can create, say 10 blogs in a free trial account (for X days) and then is charged $Y per month for the 10 blogs.
I have the Supporter plugin installed and set the # of days already in the plugin. However, I don't how to tie in the 9 additional blogs from the bulk upgrades into the free trial. Is this possible?
Also, I only see the option to allow users to pay annually for additional blogs in their account. Is there a way to change the the billing from annual to monthly in the code? If so, can you please tell me which file to edit.
