I also checked out SourceHut, but they're unfortunately not compatible with my email provider, and after some discussion with Drew (the founder) it started to sound like I'm not welcome unless I bring a real legal name and human identity. I understand how that type of collaboration can be valued and desired, but it excludes me, so I didn't pursue SourceHut any further. Something to think about if you ever consider it - no pseudonyms, no custom emails, use your real name and personal email address, or you'll be actively rejected by their software.
