Sharing a Birthday Wishlist with Family and Friends

I'm organizing a surprise birthday celebration for my sister and want to make sure our relatives and close friends all know what gifts she actually wants instead of buying random items she may never use. If I've already created a wishlist with her favorite books, gadgets, and home décor ideas, what's the easiest way to share that wishlist with multiple family members at once so everyone can view it and avoid choosing duplicate gifts?
