how to reorder forums and categories?

[Bigredclaygeorgia]

im confused their are numbers but how do I order them properly without gussing and doing trial error? thx

[.m.]

number next to category name represents category's order on the index page
number next to forum name represents that forum's order within its parent category

see also forum management guidance. it should be helpful though it was provided for an older version of MyBB
