Possible to make admin's flags worth more points?
Flags work like an on/off switch. Depending if the Flag is global or not, that on/off switch can apply to every user (each user can have a separate room w/ the lights on or off), or globally - every user is in one room, with only one light bulb, and one light switch.

Basically what you're asking is: is it possible to turn on the lights on twice?

No. In our light bulb analogy, that Flag switch doesn't come with a dimmer option ;)

What Rules allow you to do is aggregate the count of the Flag "votes" by multiple users (when not using global flags), and execute an action based on the sum of user "flags". But that is not what you're looking for.
