Signatures
You can include a default signature, such as a corporate disclaimer, that will appear in Outlook Express newsgroup or e-mail messages. A disclaimer is often used to show that messages submitted by employees over the Internet do not represent official company policies. The maximum size of the signature is 1 KB.
You can append signatures only to newsgroup messages, only to e-mail messages, or to both types of messages.
HTML vs. plain text for mail and news messages
By default, e-mail messages are composed in HTML and news postings are composed in plain text. You can choose to override these settings. For example, in an environment where bandwidth is limited or many users have simple mail programs that cannot understand HTML, changing the default to plain text may make sense.
Likewise, in a corporate environment where all users use an HTML-aware newsreader, changing the news post default to HTML may be desirable.
