Contact Me to add your own tip ideas or to comment on an existing tip. If I don't already have a similar tip in the database, I'll credit the tip to you! If you spot an error in the Archive, let me know – if I agree, I'll change the tip and credit you with the correction.
RSS feeds make it possible to "subscribe" to articles and website updates that interest you without actually re-visiting the sites that supply the articles. By adding feeds to an RSS feed reader, you will receive updates whenever they're available, rather like a personalized online newspaper.
Receiving an RSS feed is not like receiving an automatic email from a website. Subscribing to a feed is anonymous – you never have to reveal your email address, so you never become a target for spam.
