Upgrade the blog to a website?

I am looking to upgrade my blog into a full blown website. I am stuck and would like some ideas on what COACHES, SWIMMERS and PARENTS would like to see. I am continuing the blog for now, but will change over to the website when I feel it is ready. The website will also have a blog attached to it, so that won’t stop...just change over. I want the general idea to remain the same as my current blog...age group oriented and for coaches, swimmers, and parents.  I would like this to be a place where any individual experiencing age group swimming can come and get ideas and information to help aid in their progress.  ANY IDEAS PEOPLE!
