Safari Books Online is a digital library providing on-demand subscription access to thousands of learning resources.
The site we have built covers all of the needs for the club. As they go down the road, the members may want to spruce things up a bit. Here are a few modules that could round out the site even more:
Calendar Popup (part of the Calendar module)
The Calendar package also includes this module. This will make it so that when you click on an event in a calendar display, it will appear as a JavaScript pop-up rather than taking you to the node page. This is handy if you want people to be able to browse the details of events without leaving the calendar view page.
Countdown (http://drupal.org/project/countdown/)
This module adds a block that shows the time left until an event. This is a nice way to let people quickly know that the next meeting is in four days or four hours.
Flag Actions (part of the Flag module)
The Flag module can be set up to send emails, and to unpublish or delete nodes upon reaching certain flagging thresholds. Although this feature is most commonly used for things like community flagging of spam or offensive content, it can also be used to notify someone by email if, say, more than 10 people will be coming to an event and a second person needs to be asked to help supply refreshments.
Location (http://drupal.org/project/location/) and GMap (http://drupal.org/project/gmap/)
Instead of just typing a location in a text field, you can use the Location and GMap modules to let people use a Google map to select the location for each event.
