HeartCry has completed a wonderful update for their site.

You will find much more information than was previously available about the various works. The reports section is especially helpful. These reports can be used to stay up-to-date on prayer request and needs for the purpose of giving and intercessory prayer. Read over the site and consider whether or not you should adopt a work for the purpose of consistent prayer for their lives, family, and labors.
“Prayer does not fit us for the greater works; prayer is the greater work.” - Spurgeon
