Why Github resists on adding a invitations page?

This is long requested by many users but ignored. As a user I prefer a simple HTML page with 0 CSS and fancy features containing all my Github invite URLs to the situation that I have right now. At this moment the only solution that I can find is a link that I have to generate manually to desperately try to guess what my invite URL is and this is very embarrassing. Emails are not a good solution to this problem.
