I wonder how many people out there are having the same problem.

I imagine it must be a DNS issue. I moved one of my internet sites last week and it took several days for it to be visible, even for me. So this must be what is going on for you.

Call your ISP on Monday morning and tell them about this. Or maybe it's easier just to fire off an E-Mail in the morning. Just tell them your symptoms, that you cannot directly access AudioRoundTable.com. Perhaps they refresh their copy of the DNS on a weekly basis and it won't be updated until tomorrow.
