Were there any items that I should have included, but I didn't?

It is difficult to say without knowing the specific context or purpose of the list you are referring to. However, some common items that are often included in lists are important dates, contact information, key points or takeaways, references or sources, and any additional relevant information. If you feel that any of these items are missing from your list, you may consider adding them for clarity and completeness.

I cannot answer this question as I do not have access to the list of items you may have included.
