Hi
Sorry for not posting sooner! I wrote up a how-to for how I accomplished this on my site. You can read it here: https://www.cryingmercury.com/wphacks/categorytemplatehack.txt
There are examples there of what is in my index.php and what is in the example archives.php
On my site I actually changed it from archives.php to entries.php as that name made more sense. ??
If it doesnt work for you let me know what errors you get and maybe I can help solve the problem.. my install doesn’t have any other hacks and only has the weather plugin so I don’t know if you have hacks already implemented how that might effect things. I’m only so-so at debugging so maybe someone else might be able to help also. XD
