I forgot to add Liverpool FC.
So clubs like Takoma Park Friends or Takoma Park Grasp are not actually connected, and barely connected to Takoma Park Soccer Club. Friends and Grasp are organizations that are team based and don't have enough resources/interest/etc. to field teams at all age groups. In fact, almost all have very little online presence and tend to be word of mouth. In order to register their teams in EDP, they have to be housed by a soccer club like Takoma Park SC. There are others as well, just look at EDP and NCSL and see all the teams that start with Takoma Park (e.g.,
http://www.ncsl-soccer.com/_element_display/#%2F80738%2Fteams%2Fclub%2F15599475.html%3Frnd%3D1687974702999). You have to reach out to the contact for the specific team and not to Takoma Park in general.
That said, Takoma Park Friends 2010 definitely had a team in the spring as our club played them in EDP. Maybe try to find their contact on the NCSL or EDP website?
