Yes - it's a default setting and it was fairly restrictive. I've changed it some to increase it but not perhaps as much as would need to make that post. You can have 10 attachments now and up to twenty images (smilies). The reason for this restriction is in deference to mobile users and those with slow internet connections.
Hope this helps
