I like the idea that Capt. Jack threw out. I do think that it looks good to cull the numbers of inactives that are out there. I can see the issue with changing name and number, but I think that it is worth it to get rid of the thousands of currently unused IDs out there. I would not like to see 6 digit numbers, and I think that it is better to do it now than later.
Capt. Jack said that the number change is voluntary, meaning that people who like their number can keep it. I like mine and am not sure if I would change it, but I do think that we need to get rid of some of the numbers that are currently in the hands of inactives.
I saw the people saying that they do not like people being able to change their number, and I think that it is the better of the options (with the opposite being that we have 6 digit ID numbers).
