In theory, newcomers should/can/ought to take a look at the FAQ sometime shortly after joining. Yes, I know that this is probably wishful thinking, but all of the instructions can't be at the top of the first page. I suggest, and I will put this on the HELP forum as well, that something be added to the FAQ that explains the thread breakdown and gives explicit directions for the "mixed" and "split" options. I looked, but I didn't see anything about this already there. OK?
