These items were compiled from the Hidden Value and net.digest columns that appeared in The 3000 NewsWire from January 1997 through June 2000.

If an individual’s postings are quoted at length then attribution is given. If there is no attribution, then the text is a merging of information from multiple individuals including the editor.

Where known, we indicate the necessary OS level for a feature. However, the exact release in which a feature was introduced is often unclear. Most features discussed will be available to users on late 5.5 PowerPatches. If 6.0 or 6.5 is needed it is usually, though not always, stated.

Also note that, whenever possible, tips have been checked for accuracy or are known to be correct based upon the editor's experience. There may still be typographical errors, but all efforts have been made to minimize them.
