On Monday I signed up to join the US bone marrow registry. On Wednesday I received my kit, swabbed my cheek, sent back my cheek swabs and am now waiting for confirmation of being registered. Here's my experience.
Swabbing your cheek is actually the easiest part in the process. Applying for the cheek swab kit was a lot more confusing, but still pretty straightforward. The

The kit arrived two days after ordering it, which was impressive. It was also tiny - I imagined a big parcel, but it was just a little envelope that looked like the rest of my mail.
You have to swab all parts of your mouth with each swabber. No idea why this is, but it made me wonder. The process is almost so easy that it made me think i'd forgotten to do something - like write my name on it, but I guess the barcode takes care of identification and also keeps your DNA safe.
