For some reason, the forum thinks basically every thread has a new reply that I need to read. I am not about to go read every single one just to clear it, so is there any way to do it in bulk?

I dont think so.. but it definately sounds like a cookie problem on your end. Try enabling cookies for the viper site.

I dont know if there is a way to fix it.. There might be something in the user profile settings to mark the forum as read.
