I've just been forcibly logged out, and then upon attempting to log back in, confronted with a "maintenance" screen that is written in very poor English and ostensibly not a genuine Forumotion screen. I got around this by going through the "forgot your password" process and entering a new one: then the screen didn't appear. I understand that Phillips may have had similar issues.
It's not terribly surprising that free forum software, being free and therefore inexpensively maintained, has some security issues. That said, short of sending an angry message to the Forumotion staff (which I will do), I don't really know what to do about it, apart from reminding everybody about the importance of keeping your password hard to crack. I don't know if cracking my password was how this happened, but given that a password reset got rid of the screen, it sounds likely.
For more information on keeping your password difficult to crack, see this actually pretty informative comic. Mine was essentially a random jumble of letters. And if you do find yourself locked out of this forum for whatever reason, I go on CVG a lot and will see any PMs left for me there.
