dasswanth : In my definition - It should be dedicated to any sikhi cause ! (that's how i feel). BUT there's nothing wrong in helping needy.. like this topic heading "feeding homeless". but i think we should start it within our house (community)..
Personally, when u give financial sewa, don't think you are giving it to gurdwara management, *Think* you are giving it to gurusahib and it's on gurusahib jee on however he wants to use that money.. but i won't encourage you to keep giving the daswandth to the gurdwara without knowing where it's going.... do like this.. " Self Support the local sikh youth camps, youth darbars etc" like purchase stuff for them etcc..
Also i believe Daswanth doesn't necessary means in the form of $$ .. one can pay the daswanth by doing physical labor for sikh places too .. like cleaning the restrooms which no-one do
