There are some old names on that list.
It started out alphabetized, which is good, because otherwise, you end up with a lot of duplicates and if someone wants off, then you have to hunt the whole list for them.
I alphabetize all my lists.
Yup.. that is what is going to make it a pain (if we merge the list). I use LibreOffice CALC (opensource version that ISN’T Microsoft. It’s like Excel).
