Hi all,

action=helppanelquestionposter is an API meant for internal use by the GrowthExperiments extension's web UI, but it has not been formally marked as internal, so I'm announcing the recent changes [1] to it just in case:
- the 'email' and 'resendconfirmation' parameters have been removed;
- the 'email' response field has been removed;
- the API is now marked as internal.
The functionality provided by the API is not really useful outside of the web-based workflow it supports, and can be approximated with other, public APIs, so this is not expected to cause problems to any clients.
