When we post up our reviews, the persons name is used to create the post and as they aren't official accounts within the forum, they are "guests", rather than our usual account. I am sure there is a workaround for us to get it to work with our actual username but it seems more professional (in my eyes) to have them posting under our actual names, rather than a forum name.
They can be posted manually, via our actual forum usernames, but we have a neat tool that posts a thread for us automatically. So, we use that.
