to do a multiple quote post.. you see the button right next to the quote button with the + and " sign on it? click that untill it turns orange, click that on as many post as you want to quote, then when you have em all, click quote on the last post you want to quote and it will take you to the post a reply screen with all the messages you quote. then you just have to responde to them...

on another note. Use hot glue to hold your foam into place it shouldnt melt the foam. i hightly doubt elmers glue would melt the foam either.
