In an accident i can only blame on lack of coffee, the moderator of this site (me) accidentally rejected some comments. What happened is that i was going through removing duplicates of recently added comments (double clicking submit isn't very cleanly handled by the interface i guess as this happens to 1 in 10 posts...) And i ended up rejecting 6 additional comments.
so if you've placed a comment on this site in the last week or two and don't see it published, i apologize for the mishap. (or rather that missing coffee apologizes!)
At any rate, if you still wish that lost comment to show up, please resubmit it and i will make sure that i am properly caffeinated before moderating in the future.
