"email alert" when somebody posts -Next time they check their post they'll see what they've done! 
THanks for your comments, and after reading what you wrote I should have written at the beginning that I'm not familiar with this specific UG model (I'm aware of the dressier vintage Polerouters, but not this one). There's some website that's entirely devoted to these polerouters, I think it's not updated recently, but it's a nice compendium.
Have a good weekend,
