Force lowercase

First of all, thanks for a nifty and nice plugin.

Now. my nickname is “murko” with all lowercase, and I would want that to be even if it happens to kick off a sentence.

On the “about -tab” I see: “Murko” since the nic stands alone.
On the “Last posts -tab” i see: “Latest posts by murko (see all)” wich is as it should.

Now, what part of the code do I need to edit, and how should I go about to get “Murko” on the about tab to appear as: “murko” ?

I am guessing the file to edit is “starbox/models/Frontend.php” ?

Thanks for the support!
