Wow - @merill.net knocked it out of the park with @bluesky.ms ! Check it out - absolutely fantastic way to find Microsoft and Microsoft adjacent people like MVPs and RDs. Not only is the labels worth it, but registering as a MVP with the app was a breeze. 5/5 stars. Would recommend.

So who wants a verified 'Microsoft' and 'Microsoft MVP' label on their profile and all the posts?

I just finished setting up @bluesky.ms as a labelling service.

Go subscribe to the label to start seeing labels on verified MVPs and Microsofties.
