I have a theme that has a lovelly log in form in a top panel. You can see it here ( clcik the plus tab at the top ) http://www.organicwebdesigns.co.uk/owd2/

Stupidly and pointlessly it only logs into admin but I want it to log into a members area so I installed a plug in called wishlist.
They provide a mergecode / shortcode for a login form but the top panel options for the login only have a log in form on or off option with a separate part for the text.

I want to keep the log in forms place and style. How can I do this?
