Scroll to the top and just above the line at the top of the first post you see thread tools. The option to select prefix is only there for threads you create yourself. RC
That particular option should only be available to the originator of the post and the moderators, in my opinion. We'll discuss this and see if we can get it clarified
That IS correct as I said in post # 5 "The option to select prefix is only there for threads you create yourself". I changed it on this thread of my while the "edit" option was still available, and I changed it on an older thread of mine after the edit period had expired. I looked at several threads created by others and the option to change the prefix was not available to me. So the originator of the thread (and I assume the moderators) are the only ones who can add or change the prefix. It is really just a way for the OP to say the question has been answered. RC
