So I posted to 'General' and got a messge that the post has been moved to another forum but it doesn't say which one. It looks as if it has attempted to move it to a forum to which I have no access and failed. Not helpful.
Thanks for your help. I still have no idea how to find the marketplace or my post. Can you tell me where to look? It is not listed under 'Forums'. Or must I wait for some time before I have access? I think others can see my post as I have had a reply but I can't.
