Hello Oliver,

Thank you for using the plugin. With the current version of the plugin. There is no setting offered by the plugin that will restrict users from creating posts by checking any threshold value. But it can be done with some custom code. If you are comfortable with it please let me know the restriction criteria i.e. post status = any, ‘publish’ etc to calculate the user post-threshold value. I will be glad to help you.

Regards
Ravi
