Devin's effort

I am just moving back to Mulberry after a few years on Thunderbird when I 
couldn't get it to install on Win 7.  It seems to work fine now.  It is 
like coming home: I used Mulberry for many years and my preferences were 
still floating around and worked fine.

There are some things I find convenient in TB: drag and drop, some right 
click contextual tools, but most of the features are just bloat.  Mulberry 
is far more standards compliant and is far, far faster, far less memory 
intensive, and has fewer IMAP artifacts.

Keeping it alive seems like a worthy cause I'd be happy to contribute too. 
I've stayed subscribed to the mailing list for about 8 years now and will 
remain so.

Further, TB is abandonware as well.  And Mulberry remains more modern and 
far more feature-complete than Claws and Sylpheed.
