I was looking at older posts I had which included and found they were no longer registering / working.
Is there way to re-add them back on? I think that had to be done last time this came up if I'm not mistaken.
The move to the new servers meant that a lot of the custom things added in (such as the alternate smileys, for example) didn't make the trip over- they'll be implemented eventually, I'm sure, but making sure it all runs right is the priority first, bells and whistles can come later.
(NOTE: This is from someone who is not involved in the coding or any of that, so I can't give estimates or any of that, take my word with a big pinch of salt.)
