Text editors

Here it is again, this time in "Plain text format"

    #include <stdio.h>
    void main(int argc, char* argv[]){
        prinft(stdout,"hello world\n");
    }

As you can see, spacing is preserved, but you may not be happy with the font (Trebuchet for code?  Yuck).  To change the default font...

Site administration -> Appearance -> HTML editor

Put Courier first in the "Font list"

However I'm not sure this works very well, based on some comments I've seen in the forums.
