Has there been a config change to the forum to strip the white space out of posts? I can't see to put a carriage return into anything. It makes it very hard to write posts that are easy to read! Not many people will attempt to decypher the old Wall-Of-Text. Perhaps it is a FireFox3 issue?

Returns work for me, and I'm using FF3.

But, I've noticed that my double-space between sentences is reduced to just a single space. This sounds like a similar issue?

Using regular ol' return/enter should work fine, and I use Firefox 3 also. It is limited to a single line space between paragraphs, though.

See, works for me. :)
