Looks like both of you have accidentally hit ignore. Pb4, you did it for someone on another board. Canyon, you must have accidentally clicked it on 1 of pb4's posts at some point.
Go to 'Control Panel' at the upper left of this page (next to 'Log Off'). Then over on the right click on "Edit Ignored Users.' This will show you who you're ignoring, and it will let you remove the ignore.
Good luck! Let me know if it doesn't work.
