Just in case others are having trouble signing into this site (since the forum move), this is what I found:
Sign in did not work using FireFox.
Sign in did work using "IE Tab" extension to render as IE within FF.
I use NoScript, but had ormfoundation.net allowed. (Possibly it's the change back to ormfoundation.org that caused the touble - though option to allow the .org form did not come up).
I thought that either the ID or PW were incorrect, but it looks like it was just FF.
