It seems that because of the required placement of the infolinks code, using an include is not possible.
I tried it anyway, and when I used an infolinks include and re-uploaded my page, my infolinks on that page disappeared. So I was right, so it seems.
I have a hard time believing that people with 100+ pages would even put infolinks on all their pages to begin with since an include can't be used, and then God forbid a problem crop up and they have to go through all 100 pages again to take off or adjust the infolinks code.
Does anyone know if this is right or not? I sure hope not!!
thanks!!
