Drupal 7.x

In drupal 7 how can I create a member directory that registered users can view?

I am not quite 100% finished with it yet, but plan on a detailed write-up in the Drupal Showcase forum once done, but can I get some feedback of the progress so far?

The site is http://www.upholdrights.com

Once completed I will be releasing the theme here on Drupal.org if there is interest.

Thank you

I'm looking for something that should be fairly fundamental for a CMS: a content type that lets a non-technical user write a basic web page with images placed in appropriate spots.
In other words, our non-technical users should be able to create something basic like:

Hi I'm trying to update a node reference for a custom content type I have added to Drupal.

So if my custom field is named 'administrator_type' what other fields do I need to update besides these:

XXX_field_revision_field_administrator_type
XXX_field_data_field_administrator_type

If I add values in the database for an existing node the web app doesn't show the new values.
Is there some caching going on?
Or are there other tables that are affected?

I am having some problems understanding how Drupal is handling file and directory permissions.
I have been troubleshooting an issue... with a little help. Here is the thread describing part 1.

The problem I am having is I am not sure why I am getting the following error when I attempt to upload a new logo picture into the Bartik theme.

"The specified file temporary://websitelogo.jpg could not be copied, because the destination directory is not properly configured. This may be caused by a problem with the file or directory permissions. More information is available in the system log. "

1. Any idea where the system log is? How do I look at it?

This is a weird error as I should not have any file or directory permission issues. My directory permission is set to 750 throughout the site and the files permission is set to 640 throughout the site, except for the "files" directory in the /sites/default directory, which is set to 650. I tested other permission levels including 777, 655, 666 and the respose from Drupal is rather peculier..... I get an access denied error to the site when I increase the permission level....I would have thought that I could do more with less security when I set the permission to 777 but instead Drupal shuts the site down.

I have an Image Upload Field in a Content type. When I click the 'Choose File' button, I am presented with a dialog to choose a file from my computer. However, I wish to upload an image from the web, and enter a web address for this.
(I could download the image to my computer and then upload it, but I have a lot of images to process and this would add a lot of time.)
How can I do this in Drupal 7?
