Ask HN: Web based helpdesk softare that is simple?

Im looking for dead-simple, hosted helpdesk system. I just want to manage tickets. I dont need inventory, I dont need remote support, just a simple, easy to use helpdesk system. If there isn't a good solution I hope someone will build one. All the helpdesk software out there is very complicated. I want something that just enables users to log a ticket and for the helpdesk staff to update and communicate with the user. Here r the features: 1. Fast and easy submitting of tickets. 2. Enable helpdesk agent to update the ticket so that the update is emailed to the user and to the helpdesk staff. 3. Have a dashboard view that shows currently open tickets, but more importantly the activity notes for each ticket. 4. Basic reports like close-out report by agent, etc.
