Old Usernames

Does Nexon still disable the use of your old username if your account was created before e-mail became the standard?

I think they only did it by request, for those who had their usernames leaked via MTS, and don't allow those requests anymore.

Oh darn. I sent in a ticket anyways. I've gotten hacked 2 times so far, but now I've taken good security measures. I'm afraid hackers have my username.

Do you mean logging in with your username instead of your email? Because I do that on all of my accounts (five that I can remember) and haven't had any issues.
