I just discovered Freshdesk. This is a SUPER EASY support system. It offers SO MUCH. I was looking for a basic FAQ program found this system that not only does FAQ, but it provides live chat, forums, satisfaction surveys and much much more. I looked into it. I saw they had a free version and I had it setup in less than 10 minutes. I love that they have mobile apps to help you stay in touch. Right now they have an android app, and a soon to be iOs app (they do have an html5 version). Prices are not based on the amount of users, but on what services you need. If you are a solopreneur you could get by with the free version.
I love that if someone mentions you or direct messages you, you can pull that into a system and determine if you'd like it to be a ticket or not. - very cool.
Likewise you can set up an app so your private  support is on your facebook page.
It integrates with EVERYTHING so now you can not only track tickets but tie it in with your billing system (I LOVE THIS FEATURE).
The beauty of the system is it is hyper rich in features but they have a tone of documentation and videos to make sure you don't get stuck.
