(what did you put after that?)

HOW DID YOU DO THAT?!

I put what I previously wrote (square bracket rigamarole) and then I put "HOORAY" (thinking it would have worked), and then I did a coupla other lines with indents (as I thought) - but when it came to the post preview, no indents showed up at all, at all.

I will try again here:

HOORAY!

and try another way, here:

          HOORAY!

hmmm....

AHA! just did a preview and discovered that you include the text you wish to be indented, in the space enclosed by code.

'kay, got it now:

          HOORAY!

                          this board is the greatest.
