I was able to create a custom home page using the complete site you set up for me on a seperate subdomain.
One last issue is the latest blog posts section. It seems to grab random posts? Certainly not the 3 most recent posts (see attached screenshot).
I noticed a reference on another question about 'featured' posts but I don't seem to have that option.

Can you send us your website login credentials so we can check this issue and find a solution for this.
