That answers one of the two questions I was going to ask, hopefully the other one hasn't been flogged to death already. Will it at some point be possible for the server side software to convert line break and paragraph breaks automatically, so that we can just hit Enter rather than having to manually tag each break?
I was going to ask if that was something we could implement in our style sheets, but seeing that they're client side only I guess it's not possible.
One other suggestion, if it's something you can implement easily, would be to add a replacement for blockquote -- something easier to type than the word. Is it possible to create a "virtual tag", maybe something like "bq" -- that your server side filter would expand to "blockquote"?
I know that last one sounds trite, but I think it would be one of those minor niceties with the potential to make at least one part of life easier for lots of folks, and it would also quite likely pretty up the place as more folks used the tag.
