ssp, when posting pages I save as Formatted ASCII which creates a text file that can be edited in Notepad or similar (i.e. trimmed down to just the pages I want to post) then pasted into a message. In the message editor window, highlighting the pasted text then selecting HTML code will preserve formatting (not perfectly, but it's not too bad).
What this does however is push up the byte count. You're limited to 10k characters per message. All those spaces to the left (extra characters) means there's less room for your pages!
If you simply paste your text into a message without specifying HTML then your text will fall to the left margin (automatic space removal) so there's room in your message for more pages. It's less neat but a more logical alternative.
If I decide to go with the HTML code option for neatness (in theory, to attract readers) then before I do any pasting I'll use an old DOS text editor I have to block-shift text left so there are only 3 or 4 spaces instead of the usual 15 or so. Then again, not everyone is as paranoid as me. And if you're only posting so many pages and you're well under the 10k character limit then maybe you don't need to worry about those extra spaces.
I always select the Preview Post button so I'll see how things will look before I post a message.
I hope that confuses rather than helps. No, wait! Other way round!
