What Does the Yellow in Certain Threads in Forum Spy Mean?

[Firestar]

So, when I'm in Forum Spy some threads show up yellow instead of blue. At first, I thought it was only when Administators posted, but now, it is yellow when someone posts in a [WW] Thread. Why? 😕

Edit: Upon closer examination I find that most of them are by Don't panic.

Posts highlighted in yellow are those made by folk on your buddy list.
