I have no problem editing the content of my post, but can't figure out how to edit the title. Anybody know how?

Sure thing...

Open the thread, and hit the arrow to the right of "Reply"...you'll get a drop-down to "Rename":

    Thanks Hy, but I see three dots to the right of 'reply', and all I see after that is 'edit' or 'delete'. I'm sure I'm logged in. (Insert shrugging emoticon here)

    Like Hybridwood pointed out.

    Make sure you LOGGED IN,
    Go to the top of the thread to your original post.
    To the right of the original post there is "share, reply, follow" select reply then the RENAME will drop down.

    Eureka! Sorry, I wasn't following your instructions properly. Obviously, my fault, but I've got to say that I don't find navigating this site all that intuitive. Why would the process for editing the content of the post be separate from editing the thread title? Once again, thanks for the help, gentlemen! 🙂
