This is a premade forum pack, which ROBLOX can't easily change.
If this idea were to be made, they'd first have to delete this forum pack completely, find a new one with editing, italics, emoticons etc. and implement it.

...You're REALLY obsessed with gnomes, aren't you? Do you talk to your family anymore? Do I need to get you a gargoyle statue?
As for OP, support. Hell, just remove ALL the forums, and get a new pack. It's easier to tweak than to create.
