Actually, the themes here at nukemods.com (including MSTrenches) are compatible with most PHP Nuke web portal systems. Except for PCNuke (
PCN Systems), other portals (RavenNuke, PNC Clan, Nuke Evo, etc...) you have to alter something inside the (theme.php) inorder for the right block to show up.
I highly recommend RavenNuke for it's more into security. PCNuke is a good option too if you're looking for a full featured website & doesn't have the time to add extra modules.
