KA probably receives too many applications. Even when, some time ago, I was happy to volunteer for free, I just got an automated email and no response. Perhaps because of visa issues ? Or maybe there is too much supply because who would not want to help change the world ?

If you never received a (human) response from us, that's a mistake on our part. I'm sorry about that.

Unfortunately coordinating volunteers takes a lot of time and we haven't found it in our interests so far to really go down that road; in order to be able to move fast we're currently looking to hire only people with a longer-term commitment.

Right now I believe we can sponsor renewals but not initial applications. I don't know of any immediate plans to change that, sorry.
