To have your profile show up in the print directory, you must first make your profile public. 

You can do this by clicking your name once logged in (top right of the page)
Then go to "Edit profile" > Clicking on "Privacy settings" > And checking the box that says "Show profile to others"

To fill in your profile, click on your name (top right again) > Click "Edit profile" and fill in the boxes there.
MAKE SURE you click save when you are done!

You can also create and manage your photo albums by clicking on "Member Photo Albums" and uploading photos into it. These will automatically show up in the printmaker directory. 
NOTE: pngs are not accepted. It's advisable to simply upload jpegs.
