If you are old school Usenet and the text groups are your favorite playground, Thunderbird is the right newsreader for you. Thunderbird is all text newsgroups all the way, letting you post and cross post and browse messages until your heart’s content. Thunderbird is also a full featured email client as well. With sleek and simple user experience, using Thunderbird is surprisingly comfortable and is much like using your favorite email client like Apple mail or Outlook. Thunderbird is not suited for binary content downloads from the binary newsgroups, but it can be used to view images in the "pictures" groups. Simply put this is a excellent companion for being all that you can be in the text group community.
