@Marco Campos:

I had more than 1000, when I reached that value and MSN wouldn't let me add any more, I cleaned up and I ended with 700. I have over 900 today. 

@Paula: 

It's hard to convince +900 contacts to move to Gtalk/Sapo/Other Jabber service, specially when a lot of them are people who spend more time on Hi5 than MSN. And Windows Live Messenger it's a given when you have a new computer (or they ask me to install them). I tried to convert some of them to gtalk, but they just don't use it! And not having sound and webcam as easily as with WLM it's a downside in Jabber.based communication.
