About us

As Chris correctly pointed out, in a comment to our issue #675, we do not link to platforms that are not publicly accessible. Therefore, in future we will no longer link to messages on Twitter. If you want to distribute information coming from Twitter that is relevant to our readers, and you think we should report on it, please provide a non-Twitter link.If you are thinking of joining the Fediverse (especially Mastodon), Jorge Sanz has many tips on where to find accounts that cover geographical topics.
