This is a new thing for me. Thanks for sharing admin
I was told by a PR event that it was impossible for me to be legitimate press and to also be a certified public accountant and a college professor. They read my profile on linked in and took me off a longstanding guest list to an evening event at CES and E3. They were very nasty about the whole affair and even insulted me when I and others called on my behalf to vet me.
