A day after it was needed, the Mac App Store support page has gone live. It largely contains information found in the help file in the Mac App Store app itself. It does address the pesky 'error 100' issue that we reported on Thursday as well. If you don't happen to have an up-to-date OS, Apple helpfully points you in the right direction for downloads and the forums where you can discuss the pros and cons of the 1-day-old store.
