I’m thinking that a more robust user id management would be to generate random numbers then ensure that they don’t exist in the database. I am considering funding a plug-in on odesk to make this. The issue with privileges bothers me though, why not edit the “create user” function to always make random id’s for users. The concern then only lies with older users not new ones, so either make new users and attribute the posts to them when deleting the old one. Alternatively one would have to create a “migrate user” type of function.
