Hi Paul,
I’ve registered you with the site. I’ve also created some guidelines (see below) to help you through the process of publishing on someone else's site. I’ve never done it either, so we’re both learning.
I think you may be able to invite me or others into specific articles, in the event you want reviews/comments. This occurs during the draft phase, prior to hitting Publish. No pressure from me to do that.
Other than the six tags indicated below in the Submission article, you are free to add whatever tags you wish. But the site reserves one tag per piece, as we show below. Our six tags help to automate organizing things.
