Automatic assignment of tickets with Trac

Question

I'm using Trac (v0.11), and I'd like to:

1. automatically assign a ticket to someone, as it's opened, basing on certain rules
   
2. hide the "assign to" and "CC" fields from the "new ticket" screen

How can I do that (scripting, workflows, etc.)?
Thanks

Answer 1

Point 1 is solved using Components , standard Trac entities that can be associated to an automatic assignee of the Ticket.

Point 2 is solved by the powerful BlackMagicTicketTweaks plugin (it hides, disables or changes the name of fields on the Ticket form).
