Many Drupal themes implement "zebra-striping", where table rows alternate background colours. This helps to improve the readability of tables by providing a visual queue to easily see which items are in the same row, even across a large table. Unfortunately, if tables are used within content, then it is unlikely that users will manually add the appropriate even / odd CSS classes to table rows. This module transparently adds those classes, without any intervention on the part of the user.
This module allows for users to book resources for use during events. For example, a student can book a microscope for use within their lab. If there is a pre-existing event which conflicts in both time and resource, a form error is displayed and the user is forced to either book a different resource or change the event times.
Sometimes it is useful to have content types which are excluded from Drupal's search mechanism. For example, you might use the Image module to store "clipart" style graphics, or additional content types are being used to store information always displayed in conjunction with other types with Views Fusion. This module lets individual nodes or entire content types be excluded from the search engine, helping to ensure that users find relevant content quickly.
