Daily message allowance wrongly counting Previews

I was just drafting a message to another member, via the conversation page, and making copious use of the Preview button as the message involved HTML, and received the below automated message:

>This is a friendly (and automated) reminder. LibraryThing only allows members to sent 30 comments and requests per day. You have now posted 27 comments.

The system really shouldn't be counting Preview button usage against the total of allowed messages.
Or possibly the messages are actually unknowingly being sent when Preview is hit? I hope it's not this for the receiver's sanity!

Additionally, there is a typo/grammar error in the message, it wants to be "to send 30 comments" not "to sent...".

Edit: altered first line for clarity.

Thanks. That whole system is current going through some changes so it's possible some code has become intertwined. We'll take a look.

Fixed (problem was parameter name had been changed)
