I think that after searching and trying many other softwares, using 123flashchat for 4 years now it's the best solution you can get.
The prices compared with the realiability, what it offers and continues updates (free updates) are more than great.
Since 2010 i bought 3 licences of this chat for others and all of them are very happy with the software.
- simplicity to use and install
- Now the standard edition offers 4 more modules (included in price) and my standar edition doesn't have them, i have to buy them separattly which it's not quite fare.
Althought since ever I am using the 123flash is the best and the easiest the faster and the greatest one.
