Certificates Wall
This plugin will NOT BE SUPPORTED AFTER Jan 1, 2014. The CertificatesWall.com will be closed in December 2014.
The functionality of CertificatesWall.com will be recreated on MyEducationPath.com . If you want to issue certificates for your Moodle students then use the plugin https://moodle.org/plugins/view.php?plugin=mod_myeducationpath . It has same functionality as this and much more.
The module makes a course completion certificate for students.
The certificate is issued to a student's wall on CertificatesWall.com . And the certificate can be printed (in format A4).
Printable version of the certificate is downloaded as PDF file ready to print.
The digital copy of the certificate is issued to student with CertificatesWall.com service. The certificate can be shared in most popular social networks.
CertificatesWall module does similar work to Certificate module for Moodle. The difference is social integration of CertificatesWall.com service. Also this plugin has no limitation on the certificate design. The certificate template is the image and anything can be displayed on the image (logo in any place etc).
Once certificate is added to CertificatesWall.com then user can share the certificate with many people and include links in a resume.
See more details about what to do with the certificate.
