Eh, if you do it only to skim over posts more effectively, there's no point. Action's important as well, and I've seen more than a few cases where people have forgotten about the actions of other characters because they focused only on the colorful text. But if it's for readability, go for it.
@Araby264 Depends on whether or not someone responds to my PM, it'd either be closed or open.
Alright, If it opens up I'd love to apply.
