I've been meaning to post this for sometime now, but I keep forgetting: MT 3.2 rocks. The comment/trackback spam management is excellent, and pretty effective at stopping 99% of spam coming in. The new template management was a bit confusing at first, but all's well now (I still haven't converted everything or even all that much, and only this morning I fixed search, which was broken due to misconfiguration). I remember the conversion to 3.2 to be mostly uneventful except for a few minor hiccups. All-in-all, a must-have upgrade. :)
