Phew. To be absolutely clear, the BR instruction used inside the (front arrow)blockquote (back arrow) keeps the line indent. After the first blockquote instruction (that is, the one without the slash) you can get a second indent by repeating it -- thus creating a second blockquote -- . To then get back afterwards to the first indent, you then have to put in the (front arrow, slash)blockquote(back arrow) instruction, closing off the second indent. And at the end of it all you have to do the same thing, closing off the first overall blockquote instruction to get back to square one.
