In order to prevent spam private messages, users have to have x-number of posts (I don’t know what that number is) in order to have access to the private message system. So I can’t private message you, but I can private message sbdrobotics, if I wanted to. And you can’t private message anyone until a certain post number has been reached.
It may also be that you have to reach “Member” level of access.
My recommendation: post some (useful, interrogatory, or otherwise relevant) information on the forum, but don’t spam 
EDIT: Upon actually looking at the thread you’re talking about, you can’t message official moderators/administrators of the forum in order to protect them from getting spam, or at least a bunch of potentially unwanted mail. Rick Tyler is one of them. The reason you can’t respond is unknown to me.
New recommendation: if you have a related question, post a new Official QA thread. If you were just going to say thanks, don’t worry about it 
. (Don’t take that the wrong way, just saying that getting a thanks on the official QA isn’t the biggest deal in the world)
