Regarding ‘See also’ links on the top of the listing of Banknotes from the Eastern Caribbean States

I think the ‘See also’ link at the top should either include Guadeloupe, or exclude Martinique. Both are part of France, and neither have ever used the EC Dollar or its predecessors, though they are both Eastern Caribbean States geographically.
Additionally, the ‘See also’ links exclude some states which are using the EC Dollar, or which were past members of the EC monetary union. It might be logical to include them.
