Here is one plotholder's account of transplanting seedlings:

I am more of a hands on gardener and not really much into reading on theories about growing vegetables, and I was surprised to hear that certain vegetables cannot be transplanted from seed. Much to the amusement of my fellow plot holders, I told them about how I grow my vegetables from seed, in trays, then transplant them out. I did this with, turnip, carrots, beetroot, lettuce, radish. In fact the carrots and turnip have been transplanted twice so far, and they are growing great. I had that many lettuces, I transplanted them into to friends' plots last month and they are just about ready for eating. My secret weapon for doing the transplanting is my wee trowel.

John, a fellow plot holder and friend, visited my plot today and had a good laugh when he saw the size of my beetroots - they are about the size of a cricket ball and some are bigger; he seems amazed. I felt a bit daft when I told others of what I do, and I think they thought I was daft as well.

I am sure there is a moral to this story, but I don't know what it is :).
