Drupal

Adds ability to specify themes that you want to have blocks configuration synchronized for.

This module provides the ability to have more fine-grained control over what users with the permission 'administer permissions' can configure. You can decide which user roles will see a limited permissions table at admin/user/permissions, and who has unrestricted access to it. The modules allows you to lock certain permissions and / or certain roles. This means that these permissions / roles will not be available for configuration to a user with limited permission configuration rights.

This module solves the Internet Explorer limitation of loading not more then 30 CSS files per HTML page (http://support.microsoft.com/kb/262161). It is suitable for Drupal websites using lots of modules that can quickly increase the number of CSS files. The module doesn't require any configuration, just enable it and it will automatically change the way Drupal loads CSS files. It works well with built-in Drupal 6 CSS compression.
Acknowledgements

This module allows privileged users to set role or page specific visibility settings for regions, based off of what is available when configuring Blocks.

Based off of Javascript Aggregator this module will gzip your aggregated css files. For Drupal 6.x
Advantages

• It's compatible with Apache 1.3 (works great with cheap hosting).
• Compresses the content once and saves the result (less CPU load on server).
• Uses level 9 compression because it's only run once per file (smaller file size).
• In general, all you need to do is enable the module and it works (no core hacking/modifying .htaccess).

Disadvantages

The features module enables the capture and management of features in Drupal. A feature is a collection of Drupal entities which taken together satisfy a certain use-case.

Features provides a UI and API for taking different site building components from modules with exportables and bundling them together in a single feature module. A feature module is like any other Drupal module except that it declares its components (e.g. views, contexts, CCK fields, etc.) in its .info file so that it can be checked, updated, or reverted programmatically.
Requirements & compatibility

Exportables module provides easy exportables for objects that normally can't be exported. Currently, taxonomy vocabularies are supported. It does this by the following:

Notifies administrator (site_mail) of new user registrations. Starting with Version 1.2 you can now define both the address it goes to and the subject and messages emailed. Starting with 1.8 you can get emails when someone updates there profile as well.

Version 1.2 has a bug in the profile code. Please upgrade to the latest version. When upgrading from 1.2. Please going into admin/settings/register_notify and reset to default.
Issues

As with all contributed modules, when considering submitting an issue:

Displays your Terms & Conditions to users who want to register, and requires that they accept the T&C before their registration is accepted.

If T&Cs are changed users with an existing account will be asked to accept the new version, and will not be able to log in until they have.

T&C text should only be entered by administrators or other highly trusted users. filter_xss_admin() is used to filter content for display, this is a very permissive XSS/HTML filter intended for admin-only use.

The Checkbox Validate module is required.

This module adds Terms of Use and a [x] I agree check box to the registration page.

In Drupal 6, a required checkbox that's not ticked/checked will bypass validation. This module circumvents this known issue by doing its own validation for the checkbox.

Compared to the Legal module, the Terms of Conditions of this module are stored in a node. The advantages of this are:
