Tips can also be useful for oldtimers.
There is no room in the FAQ for long, drawn-out discussions of the merits of various software or hardware items. We can't clutter the FAQ with detailed techniques, even those practiced successfully by experienced members. There just is no way to archive detailed opinions, ideas, and techniques in the FAQ without the risk of making the guidelines too hard to find and understand. So the Tips Section is born. If we can unclutter the FAQ by moving some details here, we will.
