I don't lose any sleep over the fact that I'm glad to tell people I'm a master gardener, whether I'm acting in my MG duties or not. Those guidelines are there to stop people from selling products with the MG logo on their website and their uniform on, inappropriately implying an endorsement of them and their business by extension or Texas AgriLife.
Nobody here on ATP is abusing the MG program in that way. A person indicating their association falls within what I would consider to be an appropriate use of the name.
I say the above to explain why I don't have an issue allowing these microbadges to be displayed in your profile.
