1. Make a new post island from all forum on my Homepage (html only) which is not php enabled? I tried to make a post island using the external instructions and they didn't work.
I'm not sure you really can, short of using SSI, but that woudln't just be html only, it'd be shtm/shtml.
2. How can I place the 'who's on online' and 'new members' above the footer instead of on the side?
Theres a post around here where Rick posted exactly how he uses external islands on his site to accomplish just this.
