The thing about me imagining BDers is that I know how way too many of you look.
Usually, though, I imagine (or at least associate) Downers with their avvies.
There are those that I've seen photos of, but I still picture them differently (bad habbit!). For example, I just can't see
Nerwen without the fair hair of her Galadriel avatar.
Lalwende is a cross between Bilbo and Irish (take what you will of it). Others I picture as they are in photos, but still that avvie association lingers there. For example, I always associate
Pitch and
Zil with blackand white, and
Agan with orange/yellow.
There are some that I don't know how they look at all.
Mith and
Lalaith look exactly like their avvies.
Eonwe, despite his description of himself earlier in the thread, is pretty pale, possibly with glasses (but not always), pretty tall, thin, and either has a mop of very fair surly hair or very dark slick hair. I still can't decide on the hair - one day I imagine it one way, and another day it's the other...
