If you guys are real "hackers", why can't I just log in with my GitHub? I mean I don't want to fill out a custom username/password for your site when all my coding related stuff can be regulated from GitHub Auth.
I have no association to hackcampus. But if they're fairly new, that kind of feature (to save you probably less than a minute, and not applicable to a many of their applicants) might well be on the list, but shouldn't be top-priority.
