Apologies if you're also on the debian-outreach list and already saw this. If you're interested in mentoring for the upcoming round of Outreachy, please sign up to do so.
There's a wiki page with a submission system. It might even work. No promises. https://wiki.debian.org/Outreachy/Round15/projects If you know of anyone else who has a great idea or you think would be a great mentor, please share the link with them or pass their name to outreach@debian. Thanks everyone! Cheers, mdb
