That said:
Can I push my BIP proposal to reddit with you as the author in it? I don't want to cause any larger confusion and want your explicit permission first
I just gave you permission via a Reddit PM subject to (1) putting me as second author to reflect the fact that you've contributed at this point more than I have, (2) making it clear that this is a WORKING DRAFT. This could be done with a sub-title on the first page, or a water-mark on every page.
