Option to select "None" if user dont want a template?

Hi,

Setting up this, and its all working well, except, when a user sign up, and selects a template, the user cant un-select... As of now, we only have one template crated, and it is selected by default... We cant have that, we need to make the user only select the template if its relevant to his site.

Any suggestions...?

Best regards,
Joran
