+h3. Note:
+
+  validates_uniqueness_of does not ignore items marked with a deleted_at flag.  This is a behavior difference between is_paranoid and acts_as_paranoid.  I'm going to treat this as a bug until I get a chance to make it an optional feature.  Be aware of it.

 h3. and you may ask yourself, where does that highway go to?
 
 If you find any bugs, have any ideas of features you think are missing, or find things you're like to see work differently, feel free to send me a message or a pull request.
 
+Currently on the todo list:
+* deal with validates_uniqueness_of issue
+* add options for merging additional default_scope options (i.e. order, etc.)
+
 h3. Thanks
 
 Thanks to Rick Olson for acts_as_paranoid which is obviously an inspiration in concept and execution, Ryan Bates for mentioning the idea of using default_scope for this on Ryan Daigle's "post introducing default_scope":defscope, and the Talking Heads for being the Talking Heads.
