No charge for changing gender

I think keeping it as GP is fine. You get 10 GP for free just for logging on for 5 days, and plenty of opportunities to get more such as from Fabulous Friday, Contests... with the new price, you could easily change gender/skin tone/eye colour multiple times a day just using the free GP you get from participating in gameplay. With that in mind, I'm keeping it as GP for the wish. Toss a coin to your 'Rachi ;)
