Rx Annotated
Contact: three routes, depending on the question
§ 1 Where each question goes
Nobody reads mail at Rx Annotated: the site keeps no address, form or number of any kind. Your question has a better home in one of three places, each able to act on it: the app's developer, NABP, or the board of pharmacy in the state where you want a license.
The app: an account, a subscription, a bug
The developer who publishes the app looks after these, not this site. Its App Store page carries links to the developer’s own website and privacy policy.
Your e-Profile, eligibility, ATT or result
Those sit with NABP, which administers both the MPJE and the Uniform MPJE. Its Customer Engagement team works from your e-Profile; nobody here can look into it or change it.
A rule in one particular state
That one goes to the pharmacy board of the jurisdiction granting your license: it wrote the rule, and its website says how it takes questions.
Rx Annotated is a reference shelf, not a help desk: there is no mailbox behind it.
