There have been many discussions about this over time.

First off, the other forum is the developers forum, for discussing issues related to the ongoing development of phpdip.
Secondly, linking that kind of forum to phpdip (hooking in authentication, etc) is a significant piece of coding that was deemed very low priority. As there have been plenty of things that affected game play to work on (the newly DATC compliant adjuticator, automated draws/pauses, etc), this has not been a priority.
Thirdly, the primary developer of phpdip, Kestas, has indicated to the community that phpdip is no longer his primary focus. He's committed to keeping the site running, but heavy development is not a priority for him. It's up to volunteer devs to put in the heavy lifting for something like this.

If you want this so bad, register on the dev forum and start the discussion, otherwise, please stop being so disrespectful with your likely multiple accounts spamming the forum.
