You want to be able to EDIT the login form?

Create the form contents (the html contents) then put it inside yourr mod/myformplugin/views/default/forms/myform.php. Add an action in your start.php for processing this form. Now you can view this form by echo elgg_view_form('myform');

Thanks Team Webgalli and I just have to register the css with the same old method wow Im beginning to understand this elgg, too bad I have spaghetti plugins that I need to fix!
