 NEW SYSTEM TRANSITION PERIOD 

We have been redesigning our website, study portal and back-end database to make a more robust system, with better, long-term functionality, flexibility and an improved user experience.

New participants can join the new system right away and existing participants will be migrated to the new system over the few weeks. Thank you for your patience during this transition period.
