projeqtor configuration

I work as an IT support and for a good reason with the amount of clients walking in and out of our office during working ours is kind of frustrating and for this reason we decided to get a ticket system to reduce the disturbances we get during working hours. We chose to use Projeqtor because my manager find it very convenient and reliable and I should be in charge of the administration of this wonderful ticketing system you created. I have a couple of questions:-

1. how does a user send a ticket. i would be very happy and glad if i get a very detailed description on this since I am but a beginner.

2. is it possible to create two different ticket dashboards. We have two different issues to address at work and we think it would be super nice if it is possible to create multiple ticket dashboards to address different issues separately.

3.how do I set the mailing notification up so users, managers, supervisors etc get notified when a ticket is closed, in pending status etc.

Best regards
Dzahli.

I would like to thank you very much for your swift response concerning my previous questions.
I am an absolute beginner and i would like to know how and where a user can send a simple ticket from

I would also be very glad if you could walk me through the controls and automation window on the mail settings for notifications.

Kind regards
Leonard

A very big thank you for your efforts and help and I have moved a step forward with your enormous and great help. I have been able to create a couple of users and they login really fine.
My question now is how does a user(project guest) send a ticket when he only has access right to Tickets(simple) window.
