The PCPlus power allows you to receive private chats from registered or subscribed users that you do not have added, even if you have NoPC enabled. Please note that the NoPC power is required for this power to function. Alongside this, moderators, owners and main owners can always private chat you, even if you have PCPlus enabled.
By default, when this power is active both subscribers and registered users will be able to PC you with NoPC active. To customize who is able to private chat you, you must use macros.
To allow only subscribed users to private chat you, you must use the macro $pcplus=s
Users that you have added as a friend will always be able to private chat you, regardless of your PCPlus settings.
xat staff will always be able to private chat you, even if you have NoPC enabled.
