From my past experience as an Office Assistant, blank lines were used for letters and memos to denote paragraphs. In BRF books, the paragraphs are indented 2 spaces without blank lines. I did not pay any attention to this on the computer until this discussion came up. If I were going to make a hard copy, i.i. on paper, I would want the two-space indentation for the paragraphs, and I guess that would amount to what? Five spaces in print? Sue S.
