MyFitnessPal uses three Twitter handles, each for a different purpose:
@myfitnesspal - the voice of the MyFitnessPal brand
@MFP_Staff - used by our Customer Happiness team to reply to support requests. If you @mention @myfitnesspal with a support request, we will reply from @MFP_Staff
@MFP_Ops - used by our Customer Happiness team to alert the community when there are issues with the MyFitnessPal website or apps. This is a good account to follow if you'd like to be alerted when we're aware of an issue and working on a resolution.
