LiveChatScript is fully featured and yet easy to use free live chat software in the internet. Its trusted by thousands of users worldwide.
I am a complete novice at WordPress, writing html, etc. Before I had a grasp of how to use plugins I decided to add a Live Chat feature to my site. Eventually I managed this. But when it came to wanting to add one to my shop, as widget, this was beyond my skills. No problem. Find a plugin. I wanted something free. I spent hours reviewing chat option after chat option. All of them quickly ended up with me having to pay something, often something on monthly basis. I decided to ask the people at Live Chat if they could do a WP Widget. Ten days later and I have added it to my shop as a Widget. Took 5 minutes. Works perfectly and it is free. Yes there are extra features you can purchase and if you make a donation you have a little more visual control. It works, its simple to use, its free and the support is excellent.
