TicketPress

This plugin adds to WordPress the features of a complete ticket system. This allows users to submit tickets to report problems or get support on whatever they want. This plugin is so light that it will give a negligible weight for the site.

The plugin works based on two shortcodes:

[my_tickets] -> For listing all tickets [new_ticket] -> For opening new ticket

This plugin, after the installation does every setup, including creating of two pages for my tickets and new tickets in the site. Along with this, you will be presented with ready-made styling for the form. So, with this feature, you can easily startup a support system, just by activating the plugin.

Note: By default the scope isn’t created. You need to create one from Tickets > Scope Menu
