We maintain an email list to keep individuals and groups working in solidarity with Chelsea (formerly known as Bradley) Manning and Julian Assange in Wales, Ireland, Scotland and England in contact with each other. This list can experience quite heavy traffic from time to time, but there are digest options as well as receiving emails individually.
The list was originally set up for Bradley Manning solidarity work but as many active subscribers to the list are also working in solidarity with Julian Assange, the list is used for that purpose too.
