Lithium Customer Support
hey Carrie. Great question. When I used to manage the Motorola mobile dev community we would use a combo of Google+ Hangouts on AIR or Cinchcast and Blyve (full disclosure I'm a consultant for them now). Hangouts on AIR is a free yet great user experience to stream a video conversation and using Blyve's moderation and curation tools it is the perfect combo. You can embed a Blyve event into your blog or any other part of your website. Ping me for details and if you are interested in a demo.
Hi, any update on live chat functionality since the 2013 posts? Does Lithium offer a group chat functionality, or is it something developers can customize?
