The European ALMA Regional Centre (EU ARC) offers support to a large community of researchers hosted by European institutions. The support is offered to the ALMA user community through seven ARC Nodes and a Centre of Expertise which are spread across Europe, as well as the central ARC which is at ESO. The aim of this Special Session during the annual meeting of the European Astronomical Society is to bring together European ALMA users and the researchers providing support at the different EU ARC Nodes. This is a great opportunity for current and future users of ALMA to discuss new scientific results, observation and data reduction strategies, foster collaborations, and brainstorm on development and implementation of software from the user community. Additionally, it offers the opportunity to identify the need for new capabilities, some of which could be implemented in the near future, such as data combination from different array configurations, pipeline products delivery, and archive mining.
