QIP — лучший интернет месседжер на мой взгляд. But people can not get used to the new QIP Infium, because they have problems with understanding of, how to use it at all. It's all in your account QIP, which also provides a Jabber account. When you start you will see a window for selecting Profile. Здесь как раз и выбирается профиль QIP — на нем хранятся ваши пароли и настройки всех учетных записей. But you can use the QIP and without the account, To do this, simply run the QIP Infium from the desktop and click on the icon in the upper left corner of the left mouse button, then you will see a menu like this:
Выбираем”Run modifiers” and we see a window like this
You've got to choose a tick “/isolated”
and three checkboxes at the bottom, like here
Теперь жмем “OK” и все, next time you start QIP you will need to create an account for the user, and then log in and add accounts ICQ, Jabber, etc.. Account QIP will not be here.
