I like AQQ.
AQQ is beautiful, ergonomic and improved software; but i am trusting Spark unlimited and Spark hasn't ads.
I belive that Spark should be like AQQ.
I think also about that an easy configurable and improved Voice&Video Chat Feature should come as default with OpenFire and Spark.
And we need so a client also on Android.
After these Openfire&Spark will excellent solution for everybody.
Especially for Companies...
