Authentication

Hey!

I have this question which is annoying me for a long time.

I'm creating a user using INSERT SQL directly, even though I know this is not the best way to do it.

However, when the inserted user logs in, he is redirected to his "Edit Profile" page, so he needs to change his description. When he submits the form with the filled description, he don't go further. How do I solve this problem? Why this happen?

Thanks in advance.
