Hi, GSOC 2020 has been announced, I haven't seen a thread yet on macports being an org.
We discussed the topic within Buildbot community, and we think we don't have enough of our users as student, and are not attractive enough to be effective. But last years experience partnering with Macports was great, and we would like to renew it. I don't know if this still makes sense for you to have a CI-dedicated GSOC project idea, but Buildbot team will be officially happy to help with mentoring of such project. Regards, Pierre
