I can answer all questions regarding ICQ except those like: "I have lost my password, how do I get it back?" because I am not an ICQ Team member, so I cannot do anything about lost passwords.
I did an education as a Management Assistant in Informatics, I am using ICQ since ICQ2000b, but of course I know the current ICQ client the best. I also used the alpha ComPad ICQ client.
