One of the newbies here -- FlewRuby from London. I second McGrath of Harlow's suggestions. Especially those about collections.

The main thing humanitarian aid organisations need to respond to an emergency such as the Mozambique floods is money. With money they can buy the things needed in that area, be it food, shelters, water and sanitation equipment, transport or to get the personnel onto site who can help. Unless a specific request has been put out for clothing or other items, sending these things in response to an emergencies appeal just creates more work for the agency who has to sort them. And a lot of bits get binned.

Even collections at folk clubs -- one place I used to go to had a 'beer box'. With every pint a person bought they put 20p in the box. By the end of an evening a good few pounds had been collected (sterling -- tho' I'm sure weightwise as well...) Every little helps.
