I only described a bit of it.

The MRP would have a list of mods in the works with a description of who was working on them and how complete they were. It would also have an 'advertising space' that gave a list of what everyone needed for their projects (texturers, html'ers etc.) so a modder who wanted something to do could simply look down the list to see if anyone needed their talents.
Afterall it's simpler to have the modder find a task that he likes than to try to find someone who will like your idea. The profile integration would have been useful for those who wanted to see what a modder's skills were and examples of their work (via links) and other bits and pieces.
