I am not sure what happened. I am not able to reproduce the mistake. The class for cursive styling would be set by the editor.
There is two other problems:
All the editing options that I included work well except for text colour. In the editor the colour changes for example to red, but in the email the text is still black.
In the first editor, there is no initial text. But in the browser the editor enters a space.The editor user has to delete the space, so that the first line is not indented. This is how the code looks like:
// WebAssist iRite: Rich Text Editor for Dreamweaver
$WARichTextEditor_2 = CreateRichTextEditor ("fieldset_group_Nachricht", "../HTMLEditor/", "550px", "400px", "Custom", "../custom/emailMessage2_fieldset_group_Nachricht1.js", "".((isset($_GET["invalid"])?ValidatedField("emailMessage2","fieldset_group_Nachricht"):"")) ."");
