nope, if you put quotes in a setcookie where your using variables the output is that...
so for that idea instead of getting say
Bob (5) I'd get $username ($id)
I nearly posted becuase I was trying that to start with, but then managed to find an example in the manual when variables were being used and they just don't go in quotes.
:-(
I think I've found a temporary measure of just getting the id on the index page and putting it in by relating it to the username, but having it in the cookie would increase the speed slightly I think.
Thanks for the idea!
