If you need to login via email address and pass in order to post.. Why login with your standard parallels login name on the sign in page, only for it to link you to login via email ? Just skip middle sign in if parallels requires to sign in to you account, or put it back the way it was before.. one set of credentials for Parallels account, and the other for forum) as this was originally done. Unless Parallels forum is undergoing redesign or if they can come up with a valid reason to double login.
