Looked at Wiki-wiki. Looks like complete anarchy. I like it. ;-)

Could the same be done with php? Would it require too much setting up? Could we use some kind of php Nuke/postnuke solution? (I might be missing something here)

Are these valid alternatives? It really depends on what we want out of it, surely? It doesn't seem to clear to me what we actually want from the site.

We *should* consider some restriction IMHO, as there are plenty more scriptkiddies and other destructive vermin than there are responsible people...
