Can I change the name somwhere or do I have to delete this account?

On rare occasions I have heard that the Queen of fluther @augustlan will grant just one wish of this kind, but it might involve gifts.

Augustlan, the community manager, can let you change you user name if the reason is valid. PM her and explain why.

You can easily change your name once, the people above are correct, augustlan is the person to PM. More than once is frowned upon and difficult to do. So, think hard, because the next one is gonna stick.

Thanks!
