After due consideration and much soul searching, I fear that I must come down on the side of the one-spacers.

The world is running out of space and we all should do all we can to preserve what we have.

Also, take care with the use of capital letters, bold face, and other things that tend to use up lots of space on your or someone else's hard drive. All of the bytes and bits that move around the Web and the Internet can clog the channels and nodes, so please don't use it for frivolous purposes. Remember, our resources are finite and must be conserved for future generations yet unborn.
