Wear your geekiness like a badge of honor. i have been RP'ing since Junior High. i even run a game here once a week (the quest is really getting interesting.) i do maps, backstories, create new theologies, new calendars and astrologies. i have a t-shirt that says,
"Dungeon Masters don't kill characters, Monsters kill characters."

i have another shirt , given me to me by my gamers, that says

"Behind every great Gamemaster is an insane urge to kill everyone"

i can either PM you the link or post it here for the fiction writers character worksheet.
