Thank you for contacting Trulia regarding maximizing your profile completeness. When you go to your profile page and click the orange "Edit Profile" button, you will be taken to the page where you can edit your profile information. On the left side of the page, you'll see a bar entitled "Profile Completeness" and just beneath the status bar it will say what percentage your profile is at and what you need to do to get to 100%. I have emailed you a screenshot to help clarify where it is located.
Yes there is. Go to your Trulia profile and in the upper right is a link labeled "Improve your profile"
There you will find the six items on the provide checklist.
If you are stuck at the 90% level, Trulia wants you to 'check in' using a Mobile device.
