Setting for question reply/ URL and other questions

Hello,

I would like the link to the plugin to be something else that "questions" like in myblog.com/questions/
Is that possible? If not, add it to your features request links

I see I can only set up one email notification.
What happens when someone subscribes to a reply? Do they get the reply from the email notification template? If not, where do I edit this? Can I have several templates: one for new question confirmation, one for replies?

I have paid for the premium service and plugin Yet I don't see where I can add question categories?
Please tell me where.

Thank you
