I just looked and it appears I have pm's there form a year ago
How sad is that
I'm sure someone may have a better answer.
One thing that might help is this.
It is possible they may not realize you sent a pm.
I know when I get a pm I don't always pick them all up and forget there is one there still and find it days later.
If it has been a while and you know they have been here you may want to consider pm'ing again
I dunno
Just a though
