Hey, Ed
I found these about a month back.

I'm working on setting up a blog in the standard LL format.
Warning page - > 2 free gallery links - > gallery page thumbs open to jpg
No widgets or sidebars.
I'm thinking that as long as you follow this format, as if it were a static site, should be fine.
You can look at one I'm working on today.

Still lot of work to do. A single link to your posts in the header or footer should be acceptable.
Just guessing, since I haven't submitted anything yet to see.
