Brian,
Lines
can be indented on this site! You just have to know how to do it.
It's easy-peasy. Any space that you want to appear as 'white' i.e. blanked out, you just substitute with a row of, let's say, 'xxxxxx's. Then you highlight them (the 'x's, that is) and change the colour to 'white'. (Hit the big 'A' icon, which indicates colour.)
It's harder to explain than it is to do! Try it --- it really
is simple. (It's got to be, because even
I can do it!
