I'm leery around online roleplaying. Not only am I a horrible roleplayer due to being accustomed to the role of storyteller, I find that most RP forums are infested with God-Moders, also known as Mary Sues. Especially free-form RP. You know the type--

Name: Aphrodite Hera Goddessa
Age: Immortal, so age is irrelevant
Background: Parents killed, dark mysterious past, blah, blah. In short, my character is an angst princess.
Race: Quarter-angel, quarter-vampire, quarter-human, quarter-elf, with some mongrel fairy, werewolf, Sith, draconic, dryad, nymph, unicorn blood somewhere in the mix.
Abilities: is connected to (insert the main source of magic/power in the RP here, like the Force), and so is indestructible and can use all kinds of magic/psychic powers/etc. under the moon and the sun.

(Note: The name "Aphrodite Hera Goddessa" isn't made up. It's a name of a girl in a horrifyingly bad fanfic. I still can't get over the "Goddessa" part. Can we say pathetically uncreative?)
