For anyone else wondering how to do it this is answers from other forums:
-Try using the Appearance pallet. Use the pallet’s flyout menu to add a new fill. Then add a new stroke and drag that selection under the fill in the pallet. Then add a new stroke and make it thicker and drag that under the other stroke.
-I’ve always used OBJECT/PATH/OFFSET PATH. First, create outline of the logo text. Then select how far out the path duplicates from the previous one. Fill and stroke each time. It layers the original text like a pancake. Hope this helps.
