I know how members tend to double-posting or sometimes even triple-posting to quote different people in their post.

Well, here's how you can do it all in a single post.

You know the quote tag in the tags option when you reply? It's the [*quote][/*quote] right? (except the '*' symbol) To insert a name to emphasize from whom you're quoting from just do this...

In the first tag [*quote] insert this line '= Dana_Scully' or whoever it is you're quoting, so it'll look like this [*quote= Dana_Scully][/*quote] (IMPORTANT!! Except the '*' symbol, it's there so you can view the tag)

End result:
