Hi everybody,

first of all thanks a lot for all the input and ideas. Wat about doing 
the following:
If it is an external link I color code it and in addition I insert a 
dialogue box that when somebody selects an external link the dialogue 
box will appear and say e.g. the following:

This link will open in a new window (external website).
Continue? yes / no

Would that be an acceptable solution?

Kind regards

     Ginger
