Thank you for quick response, Ivan!
In the link of Christmas Bonus. I saw steps to create workflow with comments.
In step one, it said "1. I created a new metakey called WorkflowDeclineComment1" and underneath that instruction I only saw just a window scroll bar with the text "As you can see I added the metakey for news provider....."
Ivan, would you provide visual/image of what you did in step 1.
