You've lost me somewhere. If you ask a question on a Microsoft relevant site, regarding, for example, Windows 8, you will get an answer from another member or, in several cases, from a Microsoft tech. The poor folks would have to know the address of such a site. Opening "help" in any Windows OS, will give them a direction and address for that. In Windows 8, when you open Help, you will get, on the first page, two of the above addresses. If those mentioned users are less knowledgeable than to do that, then I would suggest they would have similar problems finding help for any product. The bottom line would be that, perhaps, they should at least, not be trying out a beta?
For the more knowledgeable, as you infer, the information is readily accessible throughout the web. Splitting hairs, maybe, but these early releases, although users tend to regard themselves as Beta testers, are not in the true sense that at all. They are launched to test the public response. Official Beta testers, partners, etc, who absorb and use information from forums such as these, and subsequently pass it on through the beta channels, discuss and have ample support which, hopefully, is passed back to these forums.
