Hi, I am not sure it is a good idea to put all the css files into one, even though [login to view URL] suggests this. Wordpress uses several plugins and as soon as you combine css files from several plugins, it may break the design after some plugin/theme upgrade. So I suggest to use 1 css file for each plugui/theme which gives 6 css files, I think.
This is my suggestion. Please, let me know what you think about this. Patrik
