Have you ever wanted the Y2.2 template for your Y2.1 forum?  Namster of BoardMod has created a new Y2.1  compatible template that has the look of YaBB 2.2.  Here is a reprint of Namster's post on BoardMod:

If you're like me and are still using YaBB2.1 as you wait for YaBB2.2 mods, but at the same time you really like the YaBB2.2 template, you just might like this template.
 
See it live here.

I converted over the BoardIndex and Header (as closely as possible), but haven't touched the Display, HelpCentre, and MessageIndex (not sure how to).  If anybody can give me suggestions on how to convert these other templates, I can apply them to this package.
 
The template comes with the default blue and my own green style sheets.
