Forum Ignores spaces in pasted documents?

[Ambush Bug]

So, here I am trying to update Desecration (yes, for real!), and it's giving me fits.

First I formatted the story for the forum like I usually do. I go in, search for italics and bold, pop in the usual tags. No problems there. Then I cut and paste the whole thing into the post window. It pastes just fine, looks exactly like the text in OpenOffice.

On previewing the post, however, all tabs at the beginning of paragraphs have been utterly removed. I end up with this:

“Heavy-heavy,” RD remarked. “You're not usually so pinched about procedure, Boss. What gives?”

...instead of a nice paragraph with a tab at the front. So I removed the tabs, replaced them with five spaces. Tried it again, no dice. Then, when writing this post, I tried putting spaces at the front of the paragraph manually, again, no dice.

Makes me think my prose is gonna be stuck in block format, y'know? Anyone got some help for me?
