I found I cannot get into the forum properly using Chrome. Since I see a lot of guests, I'm assuming others are also having this issue
I have no problems with Firefox or IE.
Have you tried deleting the relevant cookie? I am not using chrome, but I noticed the cookie changed and I need to log in again (using Firefox).
Yes - cleaned up cookies, though I didn't blow them all away as I have several other sites where I want to avoid cleaning up cookies for now.
