I have no idea where else to ask, so here goes.
The USB Implementers' Forum used to have a discussion forum. Last time I checked (a couple of weeks ago, maybe a bit more) most of the older posts were wiped out. I went to check today, and it's gone -- there's no mention of it in the developer section of that web site. Clicking on links that turns up in Google result in 404 errors.

So what happened?
