Feh. I'm not afraid to name names.
Starr Sapphire. Excellent roleplayer, and pays close attention to dogma.
Minerva; each of her characters has thier own distinct personality, another who reads dogma and RPs it really well.
Muirann. As chaotic as her alignment dictates, and not afraid to get a little mean
.
Daralith Del'mar: A dark elf, truely, deeply, madly. One of my favorites to banter with!
Jennara. What can you say? She is distinctive. Never seen her break char ONCE, even when I'm trying to crack up her player in tells!
Daniel. His manners and nature are so believable I keep cheering on his hopefully impending knighthood...
There are many more. I picked these off the top of my head. Lots of people you don't see often, or who slip under the radar because they RP a shyer character. Pay attention to the people around you...
