Thread title/topic can be highlighted in color, edited by Staff™, stickied atop a Forum(s), and even an Icon can be attached to it, as well ... however, for consistency, no bold option IMHO. :gl:
And to further clarify ... there is no option - either by membership or Staff™ - for bold (as there are for "Stickies", color highlighting/upgrade, Moderator/Staff™ edits, etc.) It's all by design, in other words ... for consistency throughout the Forums. :hearts:
