The most popular tax related discussion group on the Internet is the group
misc.taxes.moderated.  There are a number of ways to gain access to those
discussions.   First, if you have a properly configured newsreader,
you should find that by clicking this link. 
If you are now surprised that a program popped up you've not seen before, or
that a new portion of a program you thought handled email only showed up, you've
learned something and have a new world available to you (look around a bit and
you'll find other groups as well).
If that doesn't work...
OK, if the above link didn't work, perhaps your newsreader isn't configured
properly (you'll need to ask your Internet service provider about that) or you
need to use a proprietary access method (AOL users will tend to hit that). 
Well, even if you don't have time right now to mess with those problems, there
are still solutions that use your web browser.
