Do you want to change your username at LingQ or to cancel your account? You can change your username on the Account page. We hope that you will continue to participate in this language-language community. Incidentally, I think that you should tweak your privacy settings in order to protect yourself from spam e-mails and so forth, although this site is safer than ordinary sites on the Internet.
If you want to quit using this site, you can cancel your account on the Account page.
I agree with ytk031. I was thinking the same thing. I hope that you will stay. You seem really bright!
