You can leave a message on the end of the thread Wibblegonk posted (if you have not already done so) and they should hopefully get email notification that you have done that, although obviously the older the thread the more chance the email may not still be in use.
Otherwise, now that you have three posts on the forums (an anti-spam measure) you can click on Wibblegonk's name to be taken to their profile and there is an option to send a private message.
