First, thanks for this plugin.
It works correctly (so far) and I found all the options I needed.
However, I noticed Yop-Poll automatically creates a page called "Yop Poll Archives". This page contains all the archived polls. I was wondering why it is automatically created. Personnally, I don't need it on my blog.
I think letting the blog admin create a page and integrate a short code would be better (e.g. [yop_poll id="-4"]). Otherwise, if you delete it, it will come back once you upgrade to a more recent version. Besides, it can result in changes in menu and themes. IMO, it should not be created automatically.
What are the consequences of removing this page? Can it block votes?
