Angry is not suited to you Andrew, I only know you for being nice
Not angry, just exasperated. He's very welcome to reregister and help other users, most of whom are, by the nature of the magazine, relatively new to all this, but his defamatory posts and abuse could jeopardise this forum.
The others on which you post seem to have scant regard for the laws that pertain in the rest of publishing, and may one day come undone as a result, but as part of a major media group we have to be more cautious about these things, and calling companies or individuals 'con artists' or 'crimiinals' without any justification is a major problem here.
My intention is to run a robust, but non-confrontational, community, as much to avoid dissuading new posters as to avoid potential lawsuits, and I will act to ensure such a community is maintained.
