If you use the REPLY button at the bottom of a post, it'll automatically include it as a quote. If you simply start typing a reply in the box at the bottom, no quotes. If you want to multi-quote from more than one post, it's a little more combersome. You have to select the posts, hit reply, and then manually insert the others. (I think it's available as a pop-up from more options if you've set up the multi-quote.)
Yeah thanks, but multi quoting is easier with the option tab. Cut and paste what you want, select all and quote, simples
