I was surprised to find that About This Message Board works, as well as the
smileys 
with IE.
I cannot help but be curious why it doesn’t work with Opera 6.
There’s a bug in the javascript and its relation to some CSSes. I brought this up when they switched over to the new software, but nothing was ever done about it.
Opera 7 fixed it for me.
Regarding ATMB, you should see something that ends with “f=” in the address bar, add a “2” after the “=” sign.
As to the smileys, they’re just plain mess up for a lot of people.
