I might suggest that you contact either a local children's hospital or get in contact with Make a Wish Foundation in your area. I know my son and I gave a fair amount of figures to a kid going through cancer treatments about a year ago or so, and all Iwe had to do was drop them off. We got a thank you note from the kid which was really cool. I also had my son go through and pick the figures since my collection is really his collection.
As far as what I am doing . . . most of the collection is in bags and I have turned it over to my 13 year old son. He is getting into customizing so it is getting far more use than just sittting in a bin. I have some of my favorite figures on a book shelf in my office and that is where they are.
