I think I saw somewhere in a sidebar once a tip box called "How to write a great review" but haven't been able to find it since. At this point I've written six reviews, but none of them have received "helpful" clicks, and I'm wondering if there are tips available to make reviews more helpful? I strongly suspect that a big problem with mine is that they are much too long--I get enthusiastic and want to give a lot of information. Hints, anybody? Thanks.
