hi there -
i had a phpnuke site running (version 6 has an easy install, but you have to set up the mysql database before you start). i have migrated to postnuke, which has some more features (like dynamic user data fields) which i need for my purposes. fwiw, the phpnuke community seems to be more active and has more people developing, but the platform has less structure than the postnuke platform, so you can’t always be sure something will work when they update the core features.
if you want a link to what i’ve built let me know.
