So I'm using the wp_login_form(). All of it's working swell but...
Here's my issue - I want to change the class that is automatically populated with it's submit button. I've done so by just changing the class in the wp-includes/general-template.php but I'm sure that gets written over again once I have to update wordpress. Can I do a filter for this? Is there a good link that you can provide that will show me how to create a filter for this and possibly other things as well?
I'm a bit new to php so this may be really simple .... thanks for the help.
