+        Whilst some are content to participate as individuals, others have formed communities.
+        These groups come in a range of sizes and represent geographies from small towns to large multi-country regions.

+          with the OpenStreetMap Foundation (OSMF), giving them a link to the legal and copyright

+          There is no need to formally establish a group to the same extent as the Local Chapters.
+          Indeed many groups exist very sucessfully as an informal gathering of people or as a
+          community group. Anyone can set up or join these. Read more on the
