It's all board's that use vBulletin, not just these, and yes there is a issue. Happen's on the L2 board's often as well and other's that use vBuletin. The responses sound so much like old L2 staff's replies I had to laugh and respond. " It's not us, it's a client side issue ".
It's not your router or connection when clearly you can navigate other sites freely and have no issues, kinda funny people would say that.
