no overwrite

CiviCRM noverwrite extension

Prevent users from overwriting their record while trying to add a new participant / contribution / membership.

CiviCRM by default pre-selects your own contact details when you register to an event (or other public visible forms) if you are logged in. It is generally a good thing, but might lead to errors, for instance when a team member will overwrite their own contact record, or if a person forwards an invitation they received to someone else. This extension makes the first and last name fields read only, to prevent these mistakes.

Campaign Monitor

Existing Campaign Monitor Lists will not be touched or synced. Everytime the Campgain Monitor Settings are saved the lists are saved, lists are created for the selected groups (if they do not already exist).

Mandrill Email

This extension provides email delivery for CiviMail and/or other email from CiviCRM via the Mandrill service. Mandrill is an email service that runs on the email infrastructure that powers MailChimp. It is a high quality, low cost option for email delivery, with no loss of delivery functionality, quality or performance in comparison with alternatives. 

CiviCRM Cron

Use Drupal's cron to call CiviCRM's cron. CiviCRM's cron can (and should) be called directly from the command line, but this is a simple way to define the user, pass, and sitekey used in the CiviCRM url and call CiviCRM's cron when it's not possible or convenient to configure CiviCRM's cron.

CiviDiscount

This extension allows the admin to create and manage discount codes that can be used on membership and event pages.
