Your Wikipedia account does not meet the minimum requirements to join the ACC project. It looks like you have requested access to the internal interface of the ACC project tool, rather than the requesting interface, and as such I am declining this request. Furthermore, it looks like you've successfully created an account on Wikipedia itself, and as such I would like to take this opportunity to welcome you to Wikipedia.
You may find some of the Wikipedia help pages (such as https://en.wikipedia.org/wiki/Help:Contents/Getting_started ) useful during your stay, and of particular interest may be the introduction to Wikipedia (http://en.wikipedia.org/wiki/Wikipedia:Introduction) which has some information to help you get up to speed with the way things work on the encyclopedia.
I wish you all the best and hope you enjoy your time on Wikipedia.
