AVR-Chat

Doggone it.   I find outt hat the AVR I was planning on using for my 
project, the ATtiny15, is no longer advised fornew designs (soon to be a 
thing of the past)  Now I discover that the closest replacement, the 
ATtiny25, is not supported on the STK-500 (or, at least, it is not 
listed in the Uder's Guide that came with the STK-500).  Now what do I do?
