It should be in your alerts. The blue box is just a prefix explaining the status of, for example "sold" in the classifieds instead of looking in the thread for an item that may or may not be sold. Issues in the site suggestions will have one as well. Fixed, etc Edit: Grizzly beat me to it!
It will say "Fixed" because that "problem" has been rectified. But read the entire alert. It should read like this.. Here is mine.
Those Prefixes are only for any threads in the Site Suggestions and Classified section Forums. Any other Forum won't have them attached to alerts. So when you see a colored Prefix, be sure to read the entire alert. If someone wants to make sure you see something? They will tag you in it. This heating season, I will be tagging you a lot in Threads that are OAK realted. You and I both know the benefits first hand that an OAK provides on any heating device
@savemoney if you have your notifications set to receive alerts when you're tagged, you should receive an alert for this.
Just put an @ and start typing their name. Once you get a little into it, suggestions will start to pop up.
