Since nobody ever tells you this, here is my half of it. The guests I look forward to are courteous. They are clear about the practical things and honest about what they want from an evening. They read a little before they write. They do not haggle, and they do not vanish. That is genuinely the whole list.
Nothing on it asks you to be impressive. I would far rather read an unpolished note from someone straightforward than a flawless one from someone I cannot quite place. If you recognise yourself in any of that, you were welcome here long before you wrote.
