Yes, SMF has made their update system into 'patches' that can be more easily applied, even *with* modifications (so long as they aren't that extensive). Still, it may sometimes require custom tweaking. Honestly, if I had a board as customized as this, I'd be paranoid as could be about exploits. Fortunately the code is closed (though legally you may have to reveal it if anyone asked, depending on the SMF license?), so it can't be evaluated for breach points, but it takes only the slightest of mistakes to create a breach point. That's why I *prefer* running a forum (or any third-party code) in an isolated user context.
