JoomDonation is a fantastic way to collect donations on any Joomla based website. The integrated payment methods are VERY easy to set up and work flawlessly right out of the box. There are many options for configuration, email notification settings, and integrated translation tools. JoomDonation even has a Community Builder plugin called CB Donate which is extremely useful for community based sites.
I must also mention the EXCELLENT support for this product. When I ran in to an issue (user config error) the Ossolution support team had me straightened out right away. You couldn’t ask for better support and for the price this extension it’s a great value! I highly recommend JoomDonation and all Ossolution Team extensions.
