We are currently rebuilding the website and searching for instructors for unique courses. Our previous php based site was severely hacked (not once, but twice!) so we've removed the content for the moment. We're working on revising reefs.org's website and once that is complete, we will again pick up MACO and offer courses.
If you know of someone qualified, who is willing to teach for MACO in any topic related to reefkeeping, please don't hesitate to have them email me!
Our new website will be awesome and will include chat and other details to accelerate the course process.
