Herochat is on the list, I'll get towny in a moment. As far as multiverse, simply port your world to single player, update it, and port it back to multiplayer.
I will be able to work on the smaller plugins that don't work if needed (like the OK series) and ones that just have issues with the new event system. Bugs i can possibly deal with depending on what they are.
Looking at the code for that, there are a few things that are messing with my compiler that are going to take me a bit to see how to completely fix them. This is not a simple issue really, but I should be able to get it resolved with a bit of time and care.

That is not so. That actually has the link on it referring to the developer builds. The versions there for download (stable) will not work with 1.2.
and add herochat to the list of nonworking
- CustomMusic
- ExplosionCreator
- KittyKit
- DispenserReFill
- PersonalChests
- ChatCo
as far as I know they all work.
