Posting a reply to a newsgroup

In the message list, click the message you want to reply to.
To reply to the whole newsgroup, click the Reply to Group button on the toolbar.
To reply to the author of the message by e-mail, click the Reply to Author button on the toolbar.
To select additional newsgroups to post to, click the Tools menu, and then click Select Newsgroups. Click a newsgroup in the list, and then click Add. You can choose from only newsgroups you subscribe to or all newsgroups on the server.
Type your message.
If you are sending the message to the newsgroup, click the Post Message button on the toolbar.
If you are sending the message to the author by e-mail, click the Send button.

You can reply with a single message to multiple newsgroups only if all newsgroups are on the same news server. To post a reply to newsgroups on other news servers, create a separate reply for each news server that contains newsgroups you want to post to.
To cancel a message after it is sent, select the newsgroup where you posted it, click the Compose menu, and then click Cancel Message. Canceling a message does not remove it from a newsgroup user's computer if the user downloaded the message before it was canceled.
