As a High Rank member (anyone on the 3rd level of hierarchy and above) you will have special benefits, some of these include your own space to write messages and announcements.
Each Rank will have a specific category where they will be able to post. Other leaders will be able to view and post on these categories but will not be able to moderate these unless they belong to that category.
Yes, you will get appropriate mod rights when Pro is finished with his exams and has time to return to the site and forums for maintenance.
I will make J.T. Administrator of these forums so that he can also handle promotions that I might miss.
