Here is the link http://worldautoimmunearthritisday.org/, this begins tomorrow. It is $5 for access and $8 if you want a pin otherwise it's $7 tomorrow to get live access. You can always wait until May 21 and access the info for free but obviously you will be unable to access any of the live events.
Thanks so much for this info, dryguy! With PsA as my primary, I need to get in on this, especially for info!
