eCard Plugin for WordPress
Here’s a great and easy to use little plugin for adding eCard functionality to your WordPress site.

This plugin allows you to upload images for a user to select from. Then they can add their own personal message, and send it to any email address. When they send an eCard using this plugin, no personal information is stored in WordPress database.
Update: There seem to be some new plugin offerings in the eCard sphere – here’s one I haven’t gotten to try yet – https://codecanyon.net/item/mojdeh-wordpress-greeting-ecard-postcard-plugin/10103438 – it works with NextGen Gallery.
