[General] email_status and password_status

[Mipher]

Hello, actually I have the necessity to edit the registration page as I want to integrate it with the website and I see that in the HTML of the registration template there's under the email inputs:

<tr>
	<td colspan="2" style="display: none;" id="email_status">&nbsp;</td>
</tr>

and under the password inputs

<tr>
	<td colspan="2" style="display: none;" id="password_status">&nbsp;</td>
</tr>

Can anyone tell me what's the purpose of this?
Thanks.
