THis is kinda sad, I'm not sure if I'm going to be able to stay with TNG... I just upgraded the server to PHP5/MySQL5 (which are now pretty much standards) and TNG doesn't run on it (the user lookup dies)...
I'm pretty confident and sure I can upgrade the files myself, and may give it a go... likely Darrin didn't code for register globals to be off, but I sent him an email to hear his thoughts on it...
