Plugins that work verses plugins that do not. Is this a problem mainly becuase of the Multi-User capability, or is this becuase MUWP uses WP 2?
If it is mainly becuase of WP 2, wouldnt this list of plugins be more suitable for MUWP.

I know that not all will work becuase of the MU capabilities, but this might be a good start.
Any thoughts?
