I like the idea of having "speaking" not only in bold, but also change the font. At least for me, it makes the (con-)text clearer.
Would it be okay for you if I adopt this?
[f=font-fell color:red bold]"Text."[/f]
->
"Text."
And another thing: I do have difficulties to write in 3rd Person when the character is doing something. Would it be okay for you when I use 1st person view to describe my actions?
