You could create a “music” category and a “photography” category and then keep those categories from displaying on the main blog, and only show those categories on the Music and Photography pages.

Sounds like your host has disabled a whole lot of useful PHP functions. Contact your host and give them that error message that you got. Maybe they’ll loosen the restrictions on your hosting account.

Are you talking about displaying something like this: <tag option=”something” /> ?
In order to display those, you’ll need to use & lt; and & gt; (remove the space between “&” and the lt; or gt;)

Here’s something to get you started… this plugin updates the post with the id of the last user who modified the post. It does not address TechGnome’s concern, as it is overwritten by the last person who modified the entry.
Who Last Modified? Plugin
The plugin also includes a function to echo or return the Nickname of the person who last edited the entry (but only if the person is not the original author).
It takes a $text parameter, and a true/false echo parameter (defaults to true).
For the following examples, assume that the post was written by “User 1” and modified by “Admin.”
Here’s how you’d use it:
wp_last_modified_by(“This post was edited by “);
This would produce:
This post was edited by Admin
If the last person to modify it was the original author, or if it has never been modified, it echoes out nothing.
Nothing too fancy, but maybe you can make it work for you.
Let me know if you have any problems with it… I don’t have a WordPress 1.2 install at the moment, so it’s only been tested on the latest CVS.

http://site.com/feed/?cat=-X
where X equals the category ID number.
Conversely, if you did http://site.com/feed/?cat=X (no minus sign) you’d get a feed of ONLY that category.

That data is not recorded by WordPress. The original author stays the same, and the only thing that changes is the “modified date.”
This could be an interesting feature… perhaps one that a plugin could address.

Custom fields aren’t intended to show up in your entry. They are associated with your entry, and you can access them using PHP code.
For example, you could add an “image” custom field to an entry and then write PHP code to put that image with the entry.
For a simple way of getting that custom data, check out this fine plugin:
