One problem seems to be the way leading spaces are ignored ----use dashes, ...dots, or ___underscores instead.

As Courier is a non-proportional font, it will make a big difference. The daft thing is, the text window for posting shows everything in Courier!

To insert Courier, use:

{FONT FACE="Courier New"}Put text here{/FONT}

but change the curly brackets for pointy ones!!
Don't forget, as I often do(!) to put linebreaks in! {BR}
