Hello Carol,
Could you please post the web site again that you are referring to. I cannot see it, try typing it out.
I could give you my person opinion about the website but I strongly recommend to try seek out a Reiki practioner in your area. Some will come to you, if you are not able to go to them. I only say this from experiece, as I have been very fortunate. I received my attunement back in Montreal, Quebec, Canada and the course was in french. Then when I moved to Calgary, Alberta, Canada I wanted to get my attunement in English buy a wonderful woman who now resides in British Columbia.
I don't know if you will have the same experience by doing an on line course, but if you feel it's right then it probably is for you. It's an amazing experience and it's almost addictive. Being a channel for a good energy, is an amazing feeling which is hard to descibe...but when it happens you will understand.
Love & Light,
Gigi
