Thank you for your post. I’ll forward your question regarding the Google Plus integration to the Developer team. As soon as they come back to me with an answer I’ll let you know. I would imagine you could easily add a field to the widget by opening up rf_contact_widget.php and adding in the additional field at approx line 50 and re-saving.
Can I have a url to your site please so I can look at the alignment and suggest a css fix.
