Central Notice plays a critical role in the Wikimedia movement, enabling communities to share important messages, encourage participation in global campaigns, and support impactful initiatives. Central Notice requests are governed by a community process, where community selected Admins review requests from both Affiliates and volunteers.
Between 80% and 90% of views of Central Banners are from Community and Affiliate generated requests. However, for a long time, both requesters and Admins communicated that navigating the policies around requests could be challenging. Sometimes a request would finish with both requesters and Central Notice Administrators (CN Admins) frustrated by the process.
Between Wikimania 2024 and December, we worked with the Central Notice Administrators to better understand their existing best practices, and update the CentralNotice Usage Guidelines. You can learn more about these updates, and join a training on how to use Central Notice on March 26 at 1400 UTC.

Ever seen a banner like this over a Wikipedia article? These are created by communities and governed by a public request process, where Central Notice admins approve the message and design of banners.
Why did the CentralNotice Usage Guidelines need an update?
When we began talking to Central Notice Administrators (CN Admins) on this issue, it became really clear that a lot of best practices understood by Administrators were not part of the policy. To address this, we initiated a collaborative and comprehensive review of the existing guidelines. By gathering feedback from the people involved in using Central Notice, including CN Admins, fundraising teams, and members from various Wikimedia departments. Through first brainstorming sessions at Wikimania and online, then creating a collaborative first draft of existing operating consensus by the Admins, and candid discussions to understand the challenges and opportunities for improvement.
One of the most valuable aspects of this process was the feedback loop we established. It was important for us to not only hear from experienced admins but also to understand the experiences of new requesters. Every suggestion and concern brought us closer to a set of guidelines that would work for everyone, regardless of their level of expertise with Central Notice.
This was not a quick process. It took approximately 6 months to publish the updated guidelines. Central Notice is both very complicated, and Admins are often volunteers engaged in a lot of other movement activities, but in December we published the new Central Notice guidelines.
The updated Central Notice guidelines introduced several key improvements, such as: T
- The approval process now includes specific timelines, and emphasizes the importance of obtaining community consensus, especially for new campaigns.
- There are now banner customization policies that provide requesters with clear design standards, ensuring banners are visually accessible, and do not disrupt user experience.
- There is also guidance on banner text and translation, encouraging clarity and inclusivity in multilingual campaigns and much more.
- Furthermore, the policies for affiliates and WMF staff have been clarified, and the guidelines for fundraising and survey banners have been significantly refined.
These updates make the request process more predictable and fair, ensuring that both Admins and requesters can navigate Central Notice more efficiently.
With all the hard work that went into this process, we are incredibly proud of the outcome and excited to see the positive impact it will have on the community. Our goal was to create a framework that makes Central Notice more accessible, efficient, and user-friendly, and we’re optimistic that these changes will enhance the experience for all who intend to use Central Notice.
