I am using the standard Psych Central skin and I see some names in blue and others in black. I have not looked at the details of those in black. I see the thread starter's name as black but Sky's is blue but apparently Kimmy is seeing Sky's name in black? The fairly new user DragonPhoto when he joined had his name in black but then it changed to blue, and I too thought maybe it was for new members, but other people's names have turned to black and they have been long-term members. So I still don't know what causes it I thought somebody in this thread would have the answer!
