"Will Be Added Soon..."

Just don't do it. Don't make someone think something's there, then try to open it, and revise their idea of its status. If it's not there, just let it be not there.

This is the backwards way that many people add content to a site:

1. Make the section.
2. Make the content.
3. Add the content to the section.
4. Adjust the section to match the content.
5. Rewrite the content.

Do this instead:

1. Write all the content and get the pictures together, and do it on a page that's hidden from public view.
2. Publish the page and content.
3. Link to the page and content.

If it really needs to be expressed that something is in the works, then it warrants a blog/news post.
