But no page rank would leak ... correct ? ( being disabled but still there - no actual link goes to ucoz )
That's correct. The link isn't output on the users website at all - so there's no back links or the like.
It can be removed but it won't let me edit ( Design customization » Editing templates ) without it.
If i don't have to touch ( Design customization ) and edit just pages it works without it.
Yeah, that's what I was meaning. It still stops you from editing certain sections when it's not in the template.
