DP-L (at http://tv.groups.yahoo.com/group/DP-L) is a Yahoo Group for the Dark Perks faction, open to discussion, news, and fan fiction dedicated to Detective Tracy Vetter. "We see Tracy as a gal with attitude, dealing with difficult issues and giving as good as she gets."

DP-L was extremely active from 1999 to 2001, with diminishing activity thereafter. Since 2006, only sporadic posts have been made, with no posts in 2009. DP-L was, however, active in 2010 in preparation for War Thirteen.
