"second" first- i think that takes cut and paste. but then again i am pretty much a computer moron, and as long as ive been here just learned to use "mq" in the last year. i still dont know half of this boards features (dont ask me how to put anyone on "ignore").
however, next to the quote tab is "MQ".
click that for all the posts you want to quote. when you get to the final post you want to quote click the "quote" box you would on a normal quoted post and it will also include all those you "multi quoted".
