So what happens to number 2? Do all members shift up by one?

Probably not a big deal for most places, but unfortunately I built an item years ago that is the most popular thing on this particular website, and the numbers are tied to the member number. Thousands upon thousands of links out there on websites going to particular members. Site is http://map.datastormusers.com and one of 4 permanent links to my info on the site as an example is http://map.datastormusers.com/user3.cfm?user=1

It is even worse in that most of the third-party tools that allow posting to this map use the forum cookie to identify the member frown
