I have thought of stopping because sooner or later I'll forget, and I hate being inconsistent.
Personally I think you might as well. The boldfacing probably isn’t necessary; as far as I know, most everybody in the RP is pretty good at reading other players' posts carefully, and recognizing when characters are speaking. (Many of them use italics to signify that a character is thinking, or speaking in Sharptooth, but you're the only one who uses a special format to highlight dialogue.)
What other fandoms (as in book, movie, and/or television series that especially interest you) are you into besides LBT?
