1. The admin interface is confusing. It's all there, just finding and using it is the problem!
2. You need to search around template sites to find ones suited to your site purpose. I wanted simple, clean, business ones. Most of those available seem to have a fat graphic which covers half the screen. There are more restrained ones out there.
These are minor gripes, compared to the relief of finding what is essentially a web site in a box. It can be installed in an hour, once you get familiar with it.
