Is thunderbird any good? I just recently installed and have been using firefox because of the retarded 'you need cookies enabled' problems that kept cropping up on IE. Anyways I have outlook express which I use for email and newsgroups. One thing I hate about OE is that whenever you open it, it opens up MSN messenger in my system tray...other than that I really don't have any issues with it. Is downloading, installing thunderbird worth it?
