Hopefully I didn't just miss an obvious option somewhere (there's so many lol). But to elaborate, I'd like to simply show a list of page titles instead of excerpts on tag pages (ie. http://site.com/tags/foo)

The problem is that I have google maps and custom field data on each page, and when it shows excerpts or full, the custom field data is pulled and displayed inappropriately in the custom field sidebar widget.

Any help would be much appreciated, thanks in advance.

Use this http://forum.bytesforall.com/showthread.php?t=351 with is_tag() instead of is_category() or copy index.php as tag.php and delete all the Post Kicker, Post Byline, Post Bodycopy, Post Pagination, Post Footer parts (all these sections are commented and spaced out in the source code) and upload that tag.php

Super, that worked perfectly Flynn, sorry I didn't catch that post earlier. Thanks for the help and a great template
