User Title Colours (ALL)

[Cthulhu]

I was curious about that actually, . What I gather from here, b no longer means 'bolded text' (neither does <strong>), but has got a tl;dr semantic meaning in documents now:

The b element represents a span of text to which attention is being drawn for utilitarian purposes without conveying any extra importance and with no implication of an alternate voice or mood, such as key words in a document abstract, product names in a review, actionable words in interactive text-driven software, or an article lede.

The semantically correct thing re: styling would probably be a span with one or more classes on it (idk, <span class="username administrator yog-sothoth IA-FHTAGN">HE COMES</span>)
