I tried this extension two weeks ago, bought the paid edition last week.
I like this software, i think i can rate them 4.5 if the 5 is full marks. The admin now can not fully control chat through admin panel, i hope in the coming versions, 123 Flash Chat can give the admin more permissions to control the chat.
The other features are good,such as raising hand, video conference and animated emotions.
Like this chat software.
