Favourite free software?

What's your favourite free software? I think MSN messenger is very invaluable to me, I use it everyday the moment i'm online to the second I log off. With that being said it's probably not my favourite, I could always use an alternative (I use aim as well) I would say limewire or other p2p applications are my favourite! They make searching and finding information so fast and easy at the touch of a few buttons

I dont know what I would do without MSN messenger... I am always on it, just like Robson here :P

My favorite free program is firefox!

MSN Messenger or Ares.... cant live without them.

Seems like MSN Messenger is quite a popular app. Personally though, I am not a big fan of it because I often lose time that could be spend on way more important stuff than the usual chit chat. I guess this is more a thing that has to do with my character than with the software itself. However, it wouldn't be the first time neither that I have technical problems with it.

Cant really complain if Messenger is down for a few hours every now and again, its free afterall and a great program!

Skype, without a doubt.

i couldnt live without msn or firefox but i dont really have a fav.

Skype is a 3rd party program I heard, I used to use it.
