As of this morning you will see “QUOTE” in the menu above each reply. You just press the quote link in the reply you wish to quote and it will be transferred into the reply editor at the bottom of the thread as below. Beware, if you are in the editor in “Visual” mode your typed text will enter inside the quoted text area, so I suggest you click the “Text” tab before typing your reply.
Testing my understanding. Thanks, Keith.
