With WindLight viewer most of the face lights are useless. Thinking on this, June Dion from BareRose made a face light especially for the new viewer. This face light is free.
The package contains a helpful notecard and 4 differents face lights: a standart one, a night/sunset light, a noon light and a light for Rcmd.Set to include your own settings. Permissions are copy/mod/no transfer in all lights.
Besides this light, you can also find a helpful tutorial by Caliah Lyon in Soigné: Style in Second Life
