Ability to Search or link to NMUSERs PHARMPK and Other Exisitng Forums

@bdenney, and others have suggested that it would be useful to be able to either pull in a listing of NMUSERs , Boomer PharmPK or other sites so that this site can then be used as a central searching tool.

A second possibility would be to have it setup so that new listings in these forums appear as topics when they are sent out via the listservs
