@andmo when you discover you have posted in the wrong forum section you should click the "report to moderator" link at the bottom of the post and ask nicely for it to be moved, rather than creating a duplicate post. A duplicate post will only require the moderator to deal with it anyway and potentially waste the time of people trying to help you due to duplicate effort. It is also against the forum rules (considered crossposting).
