We are writing to you from the Digital Marketing agency Roi Scroll, on behalf of Aerobus.
We want to inform you that the https://www.mediawiki.org/wiki/Wikimedia_Hackathon_2018/Prehackathon_Olot
with the title Wikimedia Hackathon 2018/Prehackathon Olot - MediaWiki
links to an Aerobus content http://www.aerobusbcn.com/en/
, but the link no longer works, the correct link is https://aerobusbarcelona.es/?lang=en.
We suggest you update it so that your readers are not sent to a page that no longer exists.
Thank you very much for your cooperation.
