From the Model Mayhem FAQ:

Can I manage which credits appear on my profile?
Yes, your profile will display 5 credits which can be managed via the My Credits section. By default, the first 5 credits that are verified should be added to your Top 5 Credits automatically - if they are not simply click "+ Top 5" to add that person to your Top 5 from My Credits!

If you have more than 5 verified credits, you can select which credits you want to appear in your profile from the My Credits view to add that credit to your top 5, which will then make it appear on your profile.
  • To manage your Top 5, click the link in "of Top 5" as shown here:


  • You should then see something like this to manage your Top 5:


  • To delete anyone, it will be best if you are on a computer with a mouse. Hover over the X and wait for the arrow to turn into a hand - when it does you'll be able to click and it will delete that person from your list. Due to a smaller area for clicking, if you want to delete the person from #5, just move them to the #4 spot first to remove them.
  • Don't forget to click Save!

Whether you have 5 or 500 credits you can control the order in which the credits on your profile are displayed by again selecting “manage top 5” in your My Credits view.
