3rd paragraph from the top under Amplify.Request: Change "having" to "have". "This ensures that you will never having timing problems if the request definition is changed in the future."
On http://amplifyjs.com/api/request/, in the first code snippet under "Handling Status" amplify is misspelled. "amplfiy.request"... This misspelling of "ampifiy" is actually found in multiple code snippets.
Message should be plural in this sentence: For an alternative to handling issues and statuses you can subscribe to a series of globally available message that are published during the request process.
