This software is awesome we are using their software since 2010 and they are really good.
support is good and your ticket will be responded within hours from submitting.
prices compared to reliability are great you can start a chat room as low as 20$ per month.
What is really great about this software is the frequent updates they release with great new stuff and new features.
I am waiting their new version 10 which will be great as i saw from pre release screenshots
I recommend this software to every one who would like to add a powerful chat room to his website.
