Go to the little envelope up in the upper right corner, between the 'bell' and your avatar.

Click on it, then on the left side of center there's a 'pen/pencil' to edit.  Click on that, start typing in IntuitGabi.... and her address should appear.  Click on it, then draft your 'politely worded complaint' and include your contact info that they seem to mysteriously be  missing.  That way your info isn't shown publicly on the forum.  

Good luck with this.
