Can't register for Firecloud
I tried to make a FireCloud account
But it wouldn't let me login - I have seen this happen before with the ORSP portal. And they told me that it just doesn't work with Chrome on a PC. I guess this is still a problem - and probably with both portals?
But now I'm trying on IE on my PC, and it won't even let me get to the login screen - it just hangs on 'Loading Firecloud'.
