They quit proselytizing in the 70s. The new organization is the old Christian Children's Fund and five other children's help organization under the new name.
I have a problem with donating money now because I associate it heavily with churches. Honestly I feel like one of the reasons I'm atheist is so that I don't have to participate in organizations like that. I would be more than willing to donate my time, but not my money. I understand that it's going to important causes, but I still don't like the idea. I would elaborate but my opinion on this is more emotional than one coherent argument sadly.
Brendon - if you live in the United States there are two really fine 'organizations' (American Atheists & Freedom From Religion Foundation) that use your 'membership' dues to produce fine monthly newspapers which keep you up-to-date on all things atheist.
One very important thing these two organizations do is fight state/church problems. Forced prayers in schools - infringements of Christians attempting to put their 10-commandments in all public places/buildings etc. This often requires law suits on behalf of all non-believers to STOP these aggregious infranctions.
You're not 'donating' money - you are becoming a member of an organization that fights directly for you against god-believers who certainly want to assimilate you. (Borg)
One of these also publishes 'Black Collar Crime' listing all those priests and pastors that continue to commit pedophalia against minors. You are in the loop of knowledge.
