Again, there's not nearly enough information to work with. I want paragraphs. If you need to draw pictures, then draw pictures. Tell me exactly what user groups you imagine there being, and what each of them should be able to do. Forget about what you know how to do already — much of that probably has to be done in a completely different way in order to manage permissions. I can't even suggest an off-the-shelf product (free or paid) with what you've given. WordPress might work, but then again you may need to purchase and install a complete version of IBM Domino Utility Server on a dedicated machine for all I know.
