So if I understand you correctly you're saying that you don't want any
such functions add at all.

Yes, I'm using that page but when I open it it just complains that I
don't have the right permissions. This happens even if I have logged

and click either preview or submit. No matter what, trac tells me I
don't have permission to create a new ticket.
