Aha! Maybe, it's your turn to fall into the trapp of the French grammar.
About the verb "oublier", it belongs to the 1st group of French verbs (those who end with "er", and consequently (according to our grammatical rules) it takes no "s" at its end when conjugated at the imperative mode, second person singular.

"N'oublies jamais..."
"N'oublie jamais..."

So Maybe:-) n'oublie jamais this rule!

Oops... Francky5591!

Thanks a lot for getting me out of the snare! Of course that's the rule, but this time the enthousiasm and the hurry made me stumble... et j'ai simplement «oublié» l'impératif...!

Thanks again/Merci encore
:-)
