I'm glad that I can help.... I'm not an expert either but I try...

To quote someone's text it's the box "quote" on the bottom right hand side of the message they post. There's a button next to it that allows you to quote multiples. Just click on all the posts you want to reply to, and on the last one click on the single quote and they will all show up in the same message.

Thanks for answering all the questions about the sdm points. I would have been stressed trying to answer them all, for I am far from an expert! How do u quote their questions? I can't seem to figure out how lol, but I am on my iPhone... If that changes things.
