To all those having trouble with PM's:
When you get a PM, read the whole thing! You will see that there are a couple of ways to respond to the person who sent the PM. There is a link that allows you to PM them back, or you can respond directly to their email address, which is embedded in the PM.
Do not just hit reply to the PM! Your reply will go to the forum utility that generated the PM, not to the person that sent the PM.
Mark, I have had a hard time with PM messages. Ill send one to someone and never get a reply. I think a lot of people do not understand that "reply" does not go to the person, but as you said it just goes to the server or utility. Maybe bringing this up will help....
I do not know how to fix it but every forum PM that I get goes to my spam folder. I sometimes catch them but most of the time I just delete spam without spending the time to check each e-mail.
Paul, I don't know about your particular setup, but on mine, if I check my spam folder and see something that isn't spam, I can select the message and click on a button that says, "not spam". From then on, messages from that source will go to my inbox instead of my spam folder.
