is there way to make CB (or Joomla core) to use and display a long encoded user id instead of a sequential user id... I don't want a robot can predict and scan my user profiles page like http://joomla/userprofile/user,123/ ,instead I like like the user id looks like asdfa123jxc234SFG
maybe under the cover the user id is still sequential, but I'd like to at least the encoded unique id is shown on the surface..
any thought on this?
