Hey, I've seen this once and couldnt recall how to set it: There is an option to post a flag-tag with a comment on the AdWord history graph. It is quite useful for instance when I make several amendments in the campaign and I want them to be recorded in the long haul. For example, when there is a change in the traffic, I can check the flagged comment to have a better understanding of what changes exactly were made in that point of time. Does anyone know how to turn this option on? Thanks!
