Thanks for the response.  Going with the flow is certainly preferable, 
but I'd rather avoid bugs down the road if I can.  After looking at the 
bug tracker, it looks like there are quite a few major/critical bugs 
that were fixed in 3.0.  Is it only those bugs with 2.2.x specified as 
the version that I should look at?  Sorry if that's an obvious question 
- I just want to make a semi-educated decision about what problems I 
might encounter if I stick with 2.2.3.
