To make sections on your page go to the 'wall' posting area and hit the # button before your text.... kinda like hashtagging .. it will increase the font. (example: #Tribe Chat)
'comments should pertain to the header you just made so make a section for all your tribes wants/needs... examples are Tribal Chat, Attacks on the Tribe, Attacks by the Tribe, Spy Reports, Rules, Tips, etc..
you can move comments in the wrong area by copy/paste to the right section then delete...
of course you have to be an admin to delete others comments but anyone can increase text size by just using the #feature
