I would be inclined to pick the documentation option but it is obviously a trick question, you should know that finding this form is a trick in itself and I am making use of this chance/opportunity, if I may.
No this application does not follow the preferred route but please don't just dismiss this outright. 15+ years envolved with PHP I'd say this request is long overdue, would you agree? We could just as easy allow another 15 pass. I'm not expecting blind trust you have all right to deny this request, no hard feelings. I consider whichever privileges you may bestow as responsibilities for which I'm accountable both in misconduct and appreciation by application of the opportunities where ever possible.
In the event I do have something to contribute, be it code, documentation, bug fixing/reporting, entertaining new features or just a simple +1 where it counts. Not having a username should not get in the way. I am passionate of all aspects PHP and therefor cannot express preference facet nor the other. Involvement will be governed by opportunity of which you hold the initial deciding factor.
Not to waste your time and attempting to make best use of my own: The main reason for requesting an account from the onset is so that I may be attributed for my efforts, if you would oblige.
In spirit of the PHP license this request therefor does not come with ANY EXPRESSED OR IMPLIED WARRANTIES of contribution that may or may not be the result of future involvement. Since publicly assigning your own name to interactions is reputation bound it should already increase responsibility and dedication but feel free to express any concerns you may have regarding my request, if I may be privileged the opportunity to persuade you otherwise or simply put any worries to rest.
I am already a proud PHP activist, this is merely the next step in evolution. I thank you for your consideration and the opportunity to present this request to be part of something phenomenal.
