* Introduction
** ET open community, combine efforts on similar topics in working groups
** wide scope to use numerical relativity in less traditional contexts including, e.g. cosmology (e.g., inflation, structure formation,...), modified gravity (e.g. effective 4D models, cosmological models, higher-D, ...), black hole properties (e.g. superradiance, stability properties,...)
** soft deliverables: initiate collaborations; contact for potential common science proposals

* Feedback and common interests
** important to combine expertise of currently distinct communities, both on a scientific and methodological level (e.g cosmology, modified gravity, compact objects; numerical relativity, maths, (perturbation) theory and phenomenology)
** development of new mathematical methods for numerical schemes 
** apply numerical methods to tackle increasingly complicated problems in perturbation theory in modified gravity
** understanding perturbations crucial for extraction and interpretation of gravitational wave signatures
** cross-checking and benchmarking with independent codes, e.g., Einstein Toolkit and GR Chombo 
** common scientific goals:
*** evolution and perturbations in cosmological backgrounds
*** early universe cosmology
** black hole stability and superradiance / axion dark matter physics

* Frequency of meetings and next meeting
** once per month or every two months
** next meeting in the beginning of March; Helvi will create doodle closer to the date
** please consider attending the workshop [http://benasque.org/2018relativity/ ``Numerical relativity beyond GR''] in Benasque/ Spain, 3-9 June 2018
