Yolanda:
I sensed a little sadness, disappointment and worry in your post about Rumba.
American style Rumba, in beginner's and intermediate level, still requires the bending of knees alternatedly. It is International style Rumba that has the legs straight and not bending knees in that fashion. However it is my believe once American style Rumba dancers reach advance level, the technique and style become just like International Rumba.
Notice that I hesitate to use Bronze, Silver and Gold level in describing things. There are fine lines to break the level down. Different organization has placed one step in silver level while the other organization would put it in Gold.
American style Rumba has its own beauty and will be here to stay. Keep your chin up and keep dancing proudly like nobody's business.
