One of the best ways to find help is to seek out the community of partners of the Netherlands Ministry of Foreign Affairs that exists online in the Netherlands Corner on the social platform IATI Connect. It is a community of over a hundred partners who share ideas, ask questions, and find resources like webinars and tips on how to improve your publication.
You can join it, too! Especially useful if you want to bounce ideas off others who, no matter how specific your problem might be, probably have encountered the same issues. The people behind the Open Data Helpdesk are there as well and help where we can.
You become a member in two steps: first you create an account on IATI Connect, then you join the Netherlands Corner. There are other groups as well, on publishing data, but also using the published data or supporting newbies internationally.
