 We have a mentor-only Google group where we handle all announcements related to GSoC for our HSF Umbrella Organization. Please write us a mail to [[email protected]](mailto:[email protected]) if you want to add your preferred email to this list. Note that all participating mentors in 2025 HSF GSoC will have to be added to this group. Please let us know if for some reason your want your mail removed from this list.
