Don't start it. If we start to do this, the map will be ruined in few weeks. Al Nusra has presence in almost every town where rebels are but in minority numbers. We already agreed to mark their presence only in Idlib province because everywhere else they have a small number of fighters. We can only mark a place under their control if a source, for example SOHR, names only their group inside an article, for example Wadi Daif etc. Therefore joint control edits are bad ideas. There were already enough sources from Jan channels saying that their soldiers are active on Alepo frontlines and mainly keeping checkpoints around towns/villages. I belive a week ago their checkpoint was atacked with an IED.
