Can I change the user's primary group by using the Account Upgrades?
Yeah, but the bad part is that if I have 'Registered' as primary user group, and I want the rights from 'Donator' that I have to do it manuallyThe primary stays the same, it's the additional user groups that the member can be upgraded into. Depending on how you set up your Upgrades, members can belong to multiple groups.
As I posted above, the permissions are cumulative.It's more about the permissions, not about the markup.
Got it, thanksAs I posted above, the permissions are cumulative.
So for example, if you don't want normal Registered Users to be able to edit their posts, set the permission to Default.
Then for the Donator group set it to Allow and that will give them the permission.
