Some questions come up time and time again in alt.backrubs .
Often the questions are interesting and the answers are not immediately obvious. However, each time one of these questions appears, much bandwidth and reader time is wasted on repetitive responses. Your suggestions for changes to these articles are welcome. Please see question 0.2 for information about whom to contact. Question 0.3 is about what changes are planned.
