  1. „Nous recherchons d’urgence des volontaires pour écrire quelques articles pendant la semaine et/ou pour les relire le samedi. Ce numéro a été publié avec une seule relecture. Si vous trouvez des erreurs et voulez les éviter à l’avenir, aidez-nous.”
    C’est super, mais faut contacter qui ?

    1. Tu as reçu une invitation à Mattermost et deux courriels sur la façon de procéder. Bienvenue au club.

    2. Hi Lejun,
      it looks that you didn’t received our emails and the invitation to MatterMost?

  2. In issue 538 you wrote „OpenStreetMap hit 90 million changesets. The changeset was done using RapiD by Diana IRM-ED, an Indonesian mapper paid by HOT.”

    Why did you single our Diana IRM-ED as a paid mapper? Her profile says she works for HOT. Yet in the same issue, none of the paid men were singled out. Does being a „paid mapper” imply something?

    Can I recommend just congratulating her for creating the 90 millionth changeset?

    1. It’s relevant to the readership that paid and AI-assisted mapping are a significant part of the ecosystem. There was no judgment of value attached or implication.
