Interdisciplinary thinking is a key success factor for any community. "Bridging Digital Communities" is the motto of the 21st I4CS, to be held from May 26 until 28, 2021 in Bamberg/Germany, dedicated to challenging aspects around modern community systems. Due to worldwide pandemic travel constraints, the steering committee will decide on the toleration of virtual presentations, depending on the given situation in May 2021.

Bamberg is a lovely place in Upper Franconia, Germany. It is located on the banks of the River Regnitz, offering unique bridges. Its Old Town is listed as UNESCO World Heritage Site, mainly due to its intact old city wall. The town dates back to the 9th century. Its name is derived from the nearby Babenberch Castle.

Due to the rapid evolution of web technologies and rich mobile Internet devices, ICT support for communities is possible on the next quality level. In search of innovative solutions, multi-disciplinary collaboration among researchers, service providers and industry partners is essential to invent novel Internet Community Services. The I4CS is a direct follower of the former I2CS (International Conference on Innovative Internet Community Systems).
