Pardon me  to those whose replies I have no acknowledged.  I can't find the "Reply" button that allows me to reply to various posts and replies.  No doubt it's because I haven't been terribly active on the forum of late,  but if you can point me in the right direction I would appreciate it!

There is an up arrow looking thing to the right of "Quote" lower right.

Or the Quick Reply at the bottom, which I'm using now.

just scroll all the way down...
