I would like to develop a members plugin so it can be used for mailing lists, volunteers etc....
I read Customizing WP tables or adding new ones? & Objective Best Practices for Plugin Development?
What I wish to know/ understand is:
Should I use WordPress' existing users table with all the enhanced functionality that comes with it?
OR
Should I create a new table cloning WordPress' users table so not to run into issues upon WordPress updates, my plugin updates etc....
& if so, can I use the built in WordPress users core functions to manipulate the new table?
