What I have to say has nothing in common with this topic but I would like to announce an idea that came up in my mind... it's about the conversation written in the chat windows that disappear after you close it. I think that you could keep the things written in the window and when you open it again, when you want to talk with that friend, the last conversation is still there. This is just because a friend told me something that I did not copy and unfortunately I closed the window and everything disappeared, and it was important information.
