Well, that's what you get for writing something nice :-p ... I'm not up to the correct obvious terms obviously as you relate to the public - otherwise you'd just write a PM to the op - but maybe PR is something different entirely and is considered deprecating since it made you post your qualifications ... so sorry for that.
Sorry, don't mean to be spiky. But PR generally refers to someone who is employed to promote a business, and to encourage the public to support that business.
My job is less PR for Adorama, than it is customer advocacy - and I always post publically for 100% transparency - and so other customers can see that if they also experience issues of any kind, that I'm here to help.
I believe that my professional background is important, because it highlights my understanding that human relationships and expectations - and failings - are an integral part of any transaction, even those which are related to commerce.
