Personally I agree that to charge someone to change their name is not worthy of Renderosity and or the membership they thrive upon. The easiest solution is either to make a new account or add the username you prefer as your artist siggy!

I dunno but the charge thing really annoys and frustrates me because its only a username and truthfully if you choose to change it please remember the above mentioned about just adding a new siggy instead why make a new account just because I am Spunkymama does not mean I must add this as a siggy. But if I were to change this a charge would delay this abilty on my part.
