The first step is to contact Rev.Dennis to get you setup with access and get introductions out of the way as well as reserve his services for your special day.
Next, download the Wedding Ceremony Worksheet which looks like this (example of page1 of worksheet below. you can download from the Weddings club)
You should have access to the Weddings club which you will find Ceremony as a tab which is where you will look through options
Now you are viewing the Ceremony Blog, it becomes more helpful when you filter based on categories that you'll find on your Wedding Ceremony Worksheet.
Once you have the Wedding Ceremony Worksheet filled out, provide your results to Rev.Dennis and he'll put your Ceremony together for you to review and work out the finer details.
