dtgreene: Here is a topic that seems to be badly broken:
I can't even click the attachment link in the first reply to the topic.
JMich: It's a quote issue. Have had it a few times before. Basically one can have mismatching quote tags, and the closing tag will align everything a bit to the left, which when missing the opening quote will result in what you see in that thread.
Did a little test, and it seems a capital letter can fool the forum's check for matching tags.
(Normally, if the tags don't match, the forum appears to take literally forever to process the post. Personally, I would prefer it if the forum would instead return an error right away when it detects mismatched tags.)
