Hallo Peter
I'm sure, if we create a Wiki page on our home page.. it will be again only very few people contributing and even less people crawling through it. Because finding information on a Wiki also requires some kind of research by the person himself...
If you build a Wiki clever up step by step, you have nothing to search, from TRX to Dish. A newcomer begins at top (TRX) and a more advanced OM can "click" in between until he reaches the bottom (Dish). Such a Wiki needs many experienced OM's who are willing to bring in there knowlege.
