Just browse to https://support.hampager.de/open.php in our ticket system and file a new ticket. Select General Question and fill in the form. Explain what you want to do and what type of support from the DAPNET team you need. You should also give us information about the transmitter-groups you want to serve the rubric to and maybe if you want to regionalise it (for example like APRS-WX).
You should also provide the name (3 to 20 characters) and the description (for presentation within Skyper-pagers, limitted from 1 to 11 characters) of the rubric and who (which users) should be able to fill it with news.
If you have questions in scripting the API-calls, we could provide some help.
