I have the same problem too for my fantasy baseball on ESPN. I'm officially logged on but it wants to verify it's me when I try to post a message. Strange, it's no longer wanting to verify for my roster changes anymore. I called up ESPN about the problem. They told me to try another browser. I use Firefox, so I tried it on IE, and when I click the Login button in IE, it brings up the sign-in page (it works). He considered the problem fixed even though I told him I didn't considered that being fixed (just circumvented). Another team owner has a Mac with the same problem who I figured would be using Safari. Try using IE to see if that works for you.
