John, I'm not sure if it's doable, but if anyone can co it, I know it's you (suck up!). Could the bump lists be customized so that people can register on a list. Then when the list is entered in the "To:" field everyone on the list is notified.
Example: I want to notify everyone who's interested in 2nd Amendment issues that there's new legislation being intiated. I type "bang_list" in the "To:" box. Everyone who has registerd to have their name added to the list will be notified.
Could this work similar to the "All" function?
Yes! That is exactly how it will work in the future.
