I want to make it so that in order to vote in polls, you need 10 posts.
How do I do this?
Admin -> Membergroups:
Create a new membergroup, set its minimum post count to 10, base the permissions off your Regular Members group.
Admin -> Permissions - > Settings:
Make sure that the "Enable permissions for post count based groups" has been checked.
Admin -> Permissions - > Permissions by Membergroup:
Then go into the permissions by member group page, and click on the groups which you want to change, here you can change the permissions, there is a permission which is called 'Vote in polls', you will need to make sure this is off for you main member group, and on for your new member group which is over 10 posts.
