DSCs (DiEM25 Spontaneous Collectives) are groups of volunteers who organise local DiEM25 events and actions. Anyone can start a DSC and start to promote DiEM25 locally, with only few, common-sense rules on how to use the DiEM25 name.
More groups and local DiEM25 members can be found via the forum. Also check out DiEM25's elected national/international collectives and all other groups in the full organigram and MeRA25's local groups in this map.
If you want to start a group in your town, write to firstname.lastname@example.org.
