I have build myself a ASP-forum, but the new server of my client doesn't support ASP, now I want to know how I can make a simmilar forum in PHP.
Does anyone know where I can find some sort of manual PHP for ASP-freakz?! 
There are several free PHP forums available for download.
Can the server of your client support Chili!Softs ASP emulation software? Come to think of it, I believe Sun bought them out. Yep, they did. Here's a link: http://wwws.sun.com/software/chilisoft/
