I'm from Sri Lanka (Country). How can I find users of the QGIS website from my Country. I mean the users that ask questions and answering from Sri Lanka. How can I filter those people from "Users" Section.
Here is the link to a QGIS user map. Just zoom into the area of interest and click to see users of interest.
Also see a related question on the stats meta site about searching the SO data dump, Is there a way to view users by city/country?, and using the StackMaps web based map. These aren't specifically QGIS users, but people who fill in info on their GIS stack exchange profile. Unfortunately it appears no users have listed a location within Sri Lanka as of this time.
