I can prove that doug_armory works for Armory, but I can't prove that I do. If you look at the last person before the advisors on the about page on the Armory website, you will see Doug's name and near it is the text doug_armory with a link to his bitcointalk profile.

I'm interning under Doug's supervision. It appears that I am not listed on the about page, so I can't use that to prove I work for Armory. Maybe Doug or someone can state that I work for Armory, but you still might not trust them just because they themselves work for Armory. On GitHub, under the pull requests section, you will find a lot of closed pull requests from me, meaning that the code was merged into Armory, but that doesn't necessarily mean that I work for Armory, because some open source projects accept contributions from outside contributors. And still, there is nothing linking the GitHub account josephbisch to this bitcointalk account josephbisch.
