I'm wondering as well how I could have spotted this changeset comment of yours earlier. The mapper was using the #msf #missingmaps #darfur hashtags that are all noted in our MSF wiki page (https://wiki.openstreetmap.org/wiki/M%C3%A9decins_Sans_Fronti%C3%A8res#Ongoing) - but please any suggestions are welcome to keep track of changeset comments with certain hashtags better. Is there a tool that I am not aware of?
