+CRITICAL
+
+* Note translation mode. Click-and-drag to create a new note box.
+* Note translation locking. When a post is locked, either prevent note edits by other users or notify them somehow. Should be timestamped so if someone fails to unlock a post it won't stay locked forever.
+* Move help pages to the wiki.
+
+
+IMPORTANT
+
+* Require users to enter their password for some sensitive actions.
+* Ability to change your account name.
+* Ability to close your account.
+* Protection against mass assignment.
+* Eliminate password cookies.
+* Replace parent/child relationships with anonymous pools. Each post would have a related posts field. This would drive the creation of an anonymous pool.
+* Use a SSL cert for the login page.
+* Ability to copy all notes from one post to another.
+* Single post pagination mode.
+* Ability to pull related tags from the wiki.
+
+
+NICE TO HAVE
+
+* Improved pool ordering interface.
+* Ability to link users using dtext.
+* Ability to highlight pools that have been updated since your last visit.
+* Image similarity search integration.
+* Ability to search post versions by tags.
+* Tag autocompletion.
+* Better formatting on comment/forum post preview so that the widths match the actual page.
+* Searching for comments by tags.
+* Face detection script (http://anime.udp.jp/face-detect)
+* Use tf-idf to calculate tag relevance (http://en.wikipedia.org/wiki/Tf%E2%80%93idf)
+* Upload progress meter (http://github.com/masterzen/nginx-upload-progress-module)
+* Ajax upload form (http://valums.com/ajax-upload)
+
+
+MAYBE
+
+* Someone here mentioned the idea of tying tags to notes. I think this is the best way of clustering tags together on a post. I probably won't take a crack at this until after the initial deployment but it's something to keep in mind.
