There have been many improvements and changes made over this time and they're really listening to their customers on what could be added to make it even better!
I believe that 123FlashChat could be the future and we'll probably see less and less of chats running on IRC, DigiChat and stuff like that.
There are many ways in which you can customize this software to meet your very own needs.
Overall, I would recommend 123FlashChat.. the alternatives don't even come close to what 123FlashChat offers.
We're using HTML5 now and it's working out great.
To the user 'rightfoot', your comment is so recent I just can't believe what you're saying. Our support tickets are responded to on the same day (except at weekends). I feel you have a chip on your shoulder. :(
