How to customize login?

[showluo]

Is there a way for users to just enter a username instead of using email to register?
If the username were to be in some special characters, such as korean or chinese characters, possible?

Yes, you can do that under some circumstances, but how would you send the user emails (order confirmations etc.) if you don't have the email address?

Special Characters?  No problem at all.

Ok. Actually my objective is to allow SQL injection to take place. Any idea how i can write the methods out?
Is there like parameterized queries somewhere in the jar files that i can edit the SQL statement or something?
Been asking my friends about this but all to no valid.
