BUGS on the www.HeroesWorld.ru portal.

I can't post in the Social and Entertainment section - What do fans of Heroes like? - Humor. As soon as I enter the Humor forum, it "forgets" my nickname and password, and re-entering them doesn't fix the situation. If I manage to log in, a message appears: "We apologize, but the forum is closed." Just in case - I'm using the Opera browser.
