the worst thing about proposing an idea is the dreaded thought that it has been tried before and failed. when i first started computing i was so bewilded with the terms used in computing it was frightening, it still is sometimes. so that kept me away! it could be very useful to help beginners understand what they are doing with the machine they have, may also prevent silly mistakes that turn into giant ones. i'm sure that patients must be needed for this. so what do you think??
