To create a white effect around a name I create the name.
Next: selections, select all, float, so that you have the ants around the name.
Then : Selections, modify, expand by one or two.
Make a new layer under the name layer. 
Floodfill this layer with white or any other color.
Now you can do a drop shadow to really make it stand out. I use this setting a lot.
2,2,50,5
If I am going to move it to animation shop I go back to the top layer and merge down and copy into AS.
