Google Now Offers Posting In Google Groups
Google has begun offering posting options in its Google Groups (http://groups.google.com) site. All Usenet messages that are less than one month old will have the following message at the bottom: "Post a follow-up to this message." After registering, users can log in and reply to a message. Users can also start new threads by browsing to a group and choosing "Post a new message to [group name]" on the right side of the screen. Google Groups will honor the X-No-Archive header.
