Am I able to view a given end user's ID (ost_user.id) from the admin panel?
No. Unless you modify the file include\staff\users.inc.php to fit to your needs.
Thanks equisde, I suspected so but still hoped.
Actually you kind of can. If you go to Users and mouse over the user the url in the bottom left hand corner will show you the url for the link. The # there is there user id
@ntozier Thanks. That it easier than my current approach of using the browser's DOM inspector.
Should I close this thread?
