From Tickets Archive:
The simplest way to create a new ticket, you can go to the tickets archive page which is by default ‘/tickets’ and click on the ‘ADD NEW TICKET’ button. In the popup that opens, you can fill in the details to create a new ticket.
Here is the tickets list / archive page for the beta site: http://helpie.pauple.com/beta/tickets/
From Create new ticket page:
When you activate your Helpie plugin, there is a page created by default called, Create New Page.
You can use it to create a new ticket.
