For reasons that I still do NOT comprehend, Intuit shut Tax Alamanac down five (?) years ago.

The information is still there; you CAN still get to it by adding site:taxalmanac (I think that does it) to the end of your search term.  MOST threads are cached, and accessible.  The info there is still some of the best I've found.

edit... and some of the funniest.  IF you can get there, find the "stale dated checks, dead kittens, etc thread".  Who said *we (tax preparers, CPA's, etc)* don't have a sense of humor?  It rivals the "troll party" thread on this forum.
