How do I go about spelling this?
I've been going over my edits and I've seen that I've used it more than once. I've been spelling it 'Okay' but I'm wondering if it should be spelt OK or O.K. instead?
O.K. just seemed a bit stunted when I swapped it in. "Are you O.K.?" seems to read a lot more formally whereas "Are you okay?" seems more sensitive.
Does it matter which way I write it or is there a "rule" I should be following?
