[TYPO3-templavoila] How to set up an extension on every page in the site - in the template

[Jes]

Hello

I am trying to set up the "new login box" extension on every page on my 
site.
I am using Templa Voila (newest version) - but cannot work out how to 
insert that extension in the template.

I know it can be done - but I just can't figure it out.

Any help will be appreciated very much. Preferably in detail - since I 
am not a very good coder - so I need it spelled out:-)

Thank you in advance - and best regards

Jes Petersen
