A little OT
Hopefully these instructions make sense. There are essentially three areas to do this in that all relate to eachother.
Step One
Click on My OH, click on My Account, under All About You click on General Information. Enter your first & last name (or whatever name/s you want to use). Click on Update My File.
Step Two
Click on My OH, click on My Profile, click on Customize Profile (above your avatar pic). Profile is the first one listed on the left. Click on Change My Display Name Preference & select one. This relates to your User Settings in Step Three.
Step Three
When you're on the MN board, to the left of the screen you will see User Settings. Click on that. Then click on Display Name Preference & pick an option. Click Save.
Okay, see how that works.
