I found
Help Desk Software script named "HESK". It allows you to setup a ticket based support system for your website very easily and few quick steps and works without much of maintenance needed for yourself.
The think I like about them is it has all the features the big and expensive help desks software's provide. It's user-friendly, lightweight and above all its free.
- Open source and so does not need anything for per license / user based payment.
- fully-featured knowledgebase
- Spam filter feature.
- Email Notifications and subscriptions
- Rating system.
- Powerful Search
HESK.com also offers a remotely
Hosted Help Desk for a small monthly fee.
