Ask Tildes: are any of you living kidney donors?

I want to donate my kidney (not to anyone in particular, which would make the process far more straightforward), but I need help navigating the bureaucracy. Here are things I have seen about living kidney donation online:

• You can select five people to get priority access to kidneys if they need it (e.g., parents, spouse, kids)
• They will fly you to where you need to go for screening
• They will cover lost wages during recovery

Now I don't know who "they" is, or how to go about getting answers to these questions. Since I'm not tethered to a particular recipient, I can choose wherever to sign up, and I want to make the optimal choice both for myself and the recipient.

If you are a donor, especially an anonymous donor who's navigated this stuff, please reach out.
