Yesterday I was testing the ProvideSupport software from the same providesupport.com site. It had an Ubuntu installer and all but after checking out pricing I was wondering if Ubuntu or in the Linux community there was a similar product that was free that provided at least a way for customers to communicate with the operators or sellers.
For all that do not know, it basically works that you install it on your web site and customers connect to it via a "Live Chat" system that you then connect to the operators or people that will answer your call. Its pretty neat but a free version would be nicer and even more if in the debian/ubuntu repos.
