I know of three currently active for summer 2014: ALS/MND and Prince's Trust, and soon the Annos Africa auction.
(If you know any more, please shout out on Twitter.)
Here's the Prince's Trust. They've passed 95%
(ETA for correction; not sure why I was getting the previous number.)
You can donate to ALS Assoc. Here's the link: http://t.co/LFOBULUWxT pic.twitter.com/KGndGIhkd2

If the ALS birthday fund is the charity you prefer, Ben demonstrates how you can even text a donation.
Make a difference for #BenedictCumberbatch 's birthday! Instead of a card or gift, try this! #ALSGlobalAwarenessDay pic.twitter.com/fD3LrpMBRR

Their goal is $7500 and tonight they're at $7145.
Do spread the word, please. Let's get them past their goal, dear Cumbercollective!
Remember, you can email him a birthday message too... and even sign the MND charter, as Ben has. (Note that the charter doesn't seem to be for American addresses, so it may only be for UK residents.)
Ben's birthday is 19 July. Please spread the word to everyone you know in the Cumbercollective. Let's make a huge amount for all Ben's charities. Some of them are summarized here.
And make sure to send along your birthday wishes too.
