I am currently subscribed to the following discussion lists. Each of the lists are good starting points to get into contact with professionals who work on topics of the DSS Triangle. If you are new to the topic, and you have specific questions, you are most likely to get the help in one of the groups.
By the way, if you are subscribed to a group, which is not listed here and you find it usefull, please let me know. there is a certain chance, that I might subscribe myself and list it here.
