display polygons with transparent fill color

[Dylan Beaudette]

greetings!

I have some polygon data that i would like to overlay on top of some DOQQ
data. if i define the polygon data as a LINE, i can see the outlines of the
polygons on top of the DOQQ... However, when i label the polygons, the labels
are applied on top of the outlines, and not in the center of the polygons.
this makes since, as i have defined  the polygons as lines...

my question- is there anyway to label a line as if it were a polygon (i.e. at
its center)?

or, better yet - can i define polygon data with an invisible fillcolor, so
that only its outlines are displayed, and labels are placed in the center of
the features?

many thanks,
