Does anyone have experience with the usenet access it says it provides? I can't find any information on google.

When I last tried a few years ago, I could just point a news reader at news.sonic.net and it worked. I can't test it now because I'm no longer a Sonic customer. (I love many things about them, but where I live in Santa Clara, they could never offer any service faster than DSL, and I finally gave in and switched to Comcast.)
