That works!! Beyond my knowledge though.
Click "MQ" on all but the last of the posts you want to include/quote in your reply. On the last post you want to quote, click the "QUOTE" button.
The Reply box will open, and all the Multi-Quoted posts plus the last Quoted post will be pre-populated in the Reply box. Then you can type your comments in context, after each post to which you are replying/quoting.
