Okay, you said it:
So I tried it... someone please tell me a working username and password for the staging site that the link sends me to because trying to login as 7up or my previous login just does not work.
Really easy? Really?
Fixed! Go to the fix.
The link shouldn't be pointing to the staging site and will be fixed tomorrow. In the meantime just substitute community-stage for community.
