any way we can include the <em> tag in font resizing, as it doesnt currently do this, and our wp installation uses TinyMCE Advanced for its page editor, which uses <em> rather than <i>

Dear user,

Could you please give us the link to a webpage, where there is a content written with <em> tag?
Thank you.

where i have manually editied the first italicised instance of "Pantone" to use <i> tags, but this is impractical for wysiwyg editing which inserts <em> which appears several times further down. eg "rapid prototyping machine / 3D printer."

Dear user,

Please be informed, that <em> tags aren't included in the plugins functionality, but we can customize it for you and add the <em> tags. Please contact us to This email address is being protected from spambots. You need JavaScript enabled to view it., if you want to do this.
