I would like to remove the "Trial Version" as stated above. I used CSS but then other part disappear as well so this is not an option.

Then I tried JavaScript but wasn't working either. Question: is it somehow possible to do it with JavaScript (I have only limited scripting capabilities).

Or can I directly access the template that creates the different sharepoint web sites for my purposes

I would appreciate advice on this matter and thank you for your attention.
