The Atacama Large Millimeter/submillimeter Array (ALMA) provides a new powerful tool for observing the solar chromosphere at high spatial, temporal, and spectral resolution, which will allow for addressing fundamental scientific questions. Based on first solar test observations, observing strategies for regular solar campaigns are currently under development. State-of-the-art numerical simulations of the solar atmosphere and modelling of instrumental effects can help in this respect, constraining and optimizing future observing modes for ALMA. On September 1st, 2014, the Solar Simulations for the Atacama Large Millimeter Observatory Network (SSALMON) has been initiated with the aim to co-ordinate related activities and to promote the scientific potential of ALMA observations of the Sun. The network is connected to two currently ongoing ALMA development studies. As of June 30th, 61 scientists from 16 countries have joined the international SSALMONetwork. Among the affiliations are NRAO, ESO, NAOJ, the Czech ALMA ARC node at Ondrejov, ESA and many more. As part of this network, expert teams are currently preparing science cases for future regular ALMA observations, which will start after 10/2016.
