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.
