Scrub the potatoes, and place in a 6 to 8-quart saucepan. Cover with cold water, add 1 teaspoon of the salt, place over high heat, and bring the water and potatoes to a rolling boil. Turn down to medium and simmer for approximately 20 to 25 minutes, or until they are tender when pierced with a knife.
While the potatoes are cooking, combine the onions, spring onions, olives, dill, and oregano in a medium sized salad bowl. Put aside. When the potatoes are done, drain well in a colander, and allow to cool slightly. Cut the potatoes into quarters and add them to the salad bowl with the onions, olives, and herbs.
In a small bowl whisk together the olive oil, red wine vinegar, lemon juice, 3/4 teaspoon salt, and pepper. Pour over the salad and mix well. Taste and add more salt and pepper if necessary. Refrigerate until ready to serve.
