Something similar just happened to me, Jenn.
I had a comment on a card earlier today, and just now.. almost 12 hours later .. it posted again, and her signature line is all in code.
Here's the link:

When I get an email notification of a comment on a card, it usually gives the username of the person who left the comment. I thought this was odd as when tonight's email notice came, it didn't give a username.
