christian,
For one 2 one chat, you should use the web messenger instead of the CuteChat.
>>so i want to make a button "chat with user" and a one 2 one chat should be able...
This feature is not supported right now. To use the web messenger, the user need to login first then add the contact.
Hope it helps.
