Problems:

In one of the old versions of msn there was an option to have a "nickname" which was something like MSN-name you can choose and change 100 times a day.. now I only see my name & surname and I have no idea if i can have something like that old "name' cause when I click "edit" i can only change my real name and surname... and that's not what I want. How to change it? Or where should I look for? Is it possible now?

Video calls: how to start a video call? Some online contacts have the option : "start a video call/conversation" (I'm not sure how's that in english..), I guess it's what I look for, but some of them only have "send a video message"- so in those cases how should I start a call?

and by the way: is it possible to still use the older versions of MSN? like 2009?

I really hate the newest one I have..  problems nothing more. I tried to install the older one but then it says that it can't work and I should choose the newest

HELP
