Monitor Help

I am attempting to make a rule board with the advanced monitors and I can't seem to get it to work out. I want a big centered title but then I want the rules in smaller text and aligned to the right, but when I try and do that it sets the title to the same size/alignment as the rule list. any help? here is my code.

mon = peripheral.wrap("back")
--Header
mon.clear()
mon.setCursorPos(3, 1)
mon.setTextScale(2.5)
mon.setTextColor(16384)
mon.write("-Rules-")
--Rule List
mon.setTextScale(1)
mon.setCursorPos(1, 3)
mon.write("1. No Spamming")

The text scale is for all text on the entire monitor. You cannot have different text sizes on the same monitor. You might try adding a second, smaller monitor on top to display the larger text.
