I discovered that several measures in the song I'm learning are wrong. How can I fix this?

To fix a tab, click "Submit New Revision" button below the tab player and download the current revision of tab in Guitar Pro format to your local computer. Make the needed changes to tab using either commercial Guitar Pro or free TuxGuitar software. Click "Submit New Revision" button again, choose the edited file, describe the changes you've made and click "Save". Your tab will be rendered on our server and the new revision will appear on site within few minutes.
