I've just checked the forum links, and they are all sending to the correct address, so it's one of those mysteries. The letter 'o' is next to 'i' on the keyboard, and a typo is the obvious thought. You used links though, so we can rule that out.
One thing that I did notice twice over the past 3 days (Friday & Sunday), was on initial click on the login tab, I was directed to an error page, with a message to inform the webmaster. Returned back to the main page, clocked on login, and all seemed well.
Perhaps nothing, but thought worthy of a mention, if gremlins are possibly in the works!.
