what happen If I have two codechef username associated with single email id, Is there any problem ?

last month I joined code chef with my email-id and I forgot my username of codechef. I wanted to participated in snackdown event, i tried every possible username of mine but it gave username does not exist, then I signed up again with same email but new username… and now I remember my both username , Is there any problem to having two username with same email id.
If yes , then why codechef validated my new username with same email id, here codechef should give the option of Recovering codechef username or use email id for LogIN.

Thanks

This is a bug, which @admin is well aware of. Just mail them [email protected] and specify which username you want to keep, they will delete the other one.

P.S. - Delete this question once things are sorted out.
