For beta testers who aren't at the machine running the beta. If you are, use Report Bug in the toolbar instead — it attaches your logs and system info automatically, which saves us asking for them.
Use the address your beta invitation was sent to.
There's nothing in beta at the moment, so there's nothing to report against yet.
Up to 3 files, 10MB each. Reporting from the web means we don't get your logs automatically — if you can, use Help › Upload log files in Mixcraft and attach the zip it makes.
