Various female PC's from the various online campaigns I've played in:
Siduri (a human bard)
Melody (A human wizard, and unfortunately for her the chosen scion of a dark god)
Nadine (Randomling's d20 Modern D*M character)
Andaluz (A human rogue assassin-type)
From the first Planescape campaign I ran:
Eltanar (a human enchantress from Krynn)
From my current Acrozatarim game:
Melisande (aasimar sorceress/paladin)
Wyshira (water genasi cleric)
Sandslipper (earth genasi psion)
Meg'anna (human druid)
Ebri (human cleric/monk)
Note that none of the above characters are actually my PC's - I've never actually played a female character. Probably because I'm usually the DM, I guess.
