I tested the login problem and experienced not being able to login in (it kept re-directing me to the "you have logged out" screen) but once I closed the tab for this site and came back I could login again
That will happen if you click on "Log in" on the "you have now logged out" page.
AS for the others, hard to tell. r3dfield's account is enabled and active, so he should be able to log in.
When it comes to email.. It's just too many variables there. Maybe it's in the spam folder, maybe the email provider have blacklisted this domain for some random reason (which can be as silly as "it's not on our list of approved email senders")
, maybe some aggressive spam filter deleted it.. Because of all the silly stuff happening there it's not really reliable and almost impossible to debug.
