So this forum (in total, obviously not just the Central or Receiver section) is only for the Cambridge products?

This forum is just for the Central and the Receiver. The reason I mentioned Cambridge was to imply that the engineers and support personnel who are responsible for the Riot cannot be found here, and that any queries regarding the product would probably not get much attention.

Turning this BBS into a general "all-Rio-products" BBS would be counterproductive, I think. We specifically limited the scope of this BBS at the time of its creation. We did this on purpose so that the traffic would be low and the S/N ratio would be acceptable.

This isn't to say that the Riot shouldn't be discussed here at all. Since it will eventually integrate with the Central, it does have relevance. And discussion of other MP3 products from any manufacturer is also relevant. So it's fine to talk about the Riot here. I just wanted to point out that you probably won't see a lot of replies to detailed Riot-hacking questions since the Riot engineers aren't here.
