Hello,
Just to clarify, what WHO publishes is OpenMRS Express:HIV which is OpenMRS + a content payload that implements WHO's HIV care and monitoring guidelines. You can download that package here:
http://www.who.int/kms/initiatives/openmrs_disclaimer/en/index.html
and there is a support group for that specific content here:
http://groups.google.com/group/openmrs-express
Although we are involved in the general OpenMRS project
(http://www.openmrs.org) it's actually seperate from WHO. What we're pushing for is concepts that have been implemented within the OpenMRS system and others, and not so much any specific piece of software.
