There are certain friends on my friends list that have their online status totally blank, i mean it doesn't even show if they are online or offline even on their calling card, the area on the calling card where it says online/offline does not have any of that. I know they are not the type to turn off their status and also i have never heard of something like this to occur. i think it might be a bug in the system, if so can it be corrected. They are also missing from my dashboard, i know one is not the type to just go invisible on me though. I am considering it could be a bug in the system.
