"I began using CiviCRM with Wordpress in early January, and it's been a great experience. With a few weeks of part-time attention and a few hours of professional assistance from my web consultant, I was up and running with 10,000+ records and about 13 custom fields. The astounding thing about my experience has been the breadth of functionality. I was initially concerned that a lot of the functionality available in Joomla and Drupal would be riddled with glitches. I purchased "Using CiviCRM" by Joseph Murray and Brian Shaughnessy (written for Joomla and Drupal users), and I discovered that almost every functionality described in the book was available to me as a Wordpress user. The back end seems to integrate seamlessly with my Wordpress website, including an event registration page I just created. Tags, groups, smart groups, CiviContribute, and CiviEvent all seem to work well for me to the extent I have used them. Lastly, I appreciate the easy transition between editing my data in CiviCRM and toggling back to edit my Wordpress website. While there is a LOT to learn in CiviCRM, the basic day-to-day functionality of adding and editing contacts is very easy to learn and requires little additional study beyond the Wordpress website editing."
