Joshua's Journey

Having set up a website for Joshua to help with his fund raising, I'm toying with trying to merge the two.  But I need a IT inspiration drive to help.

What do you think?  Would it be confusing to have the two blogs together? Or should they be merged to reflect our family?  Also, blogging about Joshua lacks comments, the chance for people to give advice, or add support or just their tuppence worth.
