Its an excellent diagram youve put up but I fear it will probably be deleted unless you reupload it with proper copyright tagging Just a note in the comment section saying you created it generally isnt sufficient to prevent such deletion and itd be a shame to lose this and the other images youve put together It looks as if youve been alerted to this issue on your talk page for pretty much every image youve uploaded What is the difficulty youre experiencing selecting the applicable copyright tag from the dropdown menu on the upload screen
