2 thing I am trying to accomplish.
Parse a RSS feed from another site to display it on mine.
Put the latest Forum posts from my boards on the wiki main page.
I basically wanted to do the exact same thing and I posted the same question a few days ago ... the answer I was given is that for security reasons you can't include PHP in any editable page, whether you are sysop or not (someone please tell me I am wrong?? ;) )
That being said, I thought of two other options:
1. Using a flash movie to pull the php data and display it. 2. Tinker with the php in the page generation files directly.
I haven't had time yet to fully explore either option, but that's all I can help you with for now!
