pdfforge.org related: Can't change the email in my profile

THIS IS RELATED TO THE HOMEPAGE NOT THE PRODUCT.

I need to change my email due to a provider change.
When I try to do this via 'edit my account' either
* the pop-up menue does never complete
* the 'normal' page return an error

I'm posting this here as I can't find another possibility to get in touch.
