I'm using DNN 4.8.2 and am referring to "Account login" with the standard DNN user name and password (NOT the cardspace, active directory, etc. module).  Is there a way to format the user name field so that I can have it look like this:

text - [    ] - [    ]

Instead of saying "username" it would say "text" and have a "-".  That much I can do.  Here's the part that I'm hung up on.  I'd like to divide the username field in half, limit each half to 4 characters, display a "-" between the two fields, and have the DNN system combine those 8 total characters (4 in each field) back into one input field.  In my crude example above, the user would just "fill in the blanks" between the [    ] as shown.

Also, is it possible to make the account login case-insensitive?  Some of my users are having a hard time with their user names and passwords being case-sensitive.  I suspect this may be a core issue.

In the alternate, is there a custom module that can accomplish this?
