I couldn't even get onto Celticsblog from my desktop this morning. It's an older computer. I am able to get in from my laptop, which has Windows Vista.
I would ask if anyone else is getting blocked just trying to get into the home page, but I guess those people wouldn't be able to read this.
Anyway, when I tried to get in from my desktop I received the error "Internet Explorer cannot open this page" or something like that. I could only choose OK and then it closes the page.
