@69francs @pfefferle That is partly my problem. I am sure I want to use this, but nothing I have read about it has really helped me to understand how it works, let alone the tips and tricks to make it as good as possible. Lots of the comments on this thread have only confirmed that feeling for me. Finally, I use Dreamhost, so it doesn't look like I can use it yet anyway. So, my summary is, the information on it needs to be much more accessible.
