Can we add a redirect somehow? cc @jsumners

[10xLaCroixDrinker]

Do you mean a server side redirect?

There's a client side redirect added in the docusaurus config at lines 208-213

Yes, we can add a page rule in Cloudflare for this (though it will use up one of our three available).

We handle redirects here:

website/docusaurus.config.utils.js

Line 75 in 37c6dea

function manageRedirects({ existingPath, major, versions, versionsShipped, ignore = [] }) {

but: https://prowritingaid.com/organisation-vs-organization

and the previous website stands with organisations:
https://github.com/fastify/website-metalsmith/blob/master/src/website/content/organisations.md

Could you update the PR? we fixed the deploy to staging.

Plus: why we don't add a redirect from organizations to organisations instead?
this would ease the job

[gurgunday]

It was because the website uses American English everywhere else

@10xLaCroixDrinker Could you do a rebase please, and we can get this over the line. 😸
We've got rid of most of the images from static/img/organisations.

[10xLaCroixDrinker]

@Fdawgs sure thing! I can take care of that by EOD Monday
