Using the SaveSetting for Multiple users

Hello All,
I am working on creating a VBA multiple form based program to edit a text file, basically modify columns with user defined input that occurs monthly. This program would be to assist multiple users in editing this large text file. This modification of the file could be the same each month. Is there a way for multiple users to be able to pull up the saved setting that they had last month to redo the manipulation? I was not sure if .ini or registry is best way to go. I appreciate any input to point me in the right direction. Thank you.
