I'm Guillaume Rischard, I like maps! I mostly map in Luxembourg, and like to do many small edits, slowly making things better.
My OSM nickname is Stereo.
I sometimes write in my openstreetmap.org diary.
I'm also a member of the Membership Working Group where I investigated the unusual coordinated member signups close to the OpenStreetMap foundation's 2018 election.
You can message me in English, French, German or Luxembourgish.
