I haven't had much luck with this so far, but it appears that you can subscribe to your Yahoo Groups as an RSS feed by using a query string similar to this one:

http://groups.yahoo.com/group/iccm/messages?rss=1

In the above example, the "iccm" part would be replaced with whatever your desired group name is.  I haven't gotten this to work with all of the groups, but it appears to work  for at least the radio-dev group.  Ironic isn't it?

I hate getting tons of email that just collect and then I never read them.  This way I'll only have recent items in my RSS aggregator.
