this is a very long story
summary is at
http://www.havederbywilltravel.com/comm ... rules.html
wftda v1.0 ---> used at dust devil '06
wftda v2.0 ---> drafted but failed to be ratified
wftda v1.0 + DD '07 customizations --> used at DD '07
incorporated a few popular snippets of v2.0
wftda v1.0 + ECE '07 customization --> used at ECE '07
incorporated a similar few popular snippets of v2.0
but also did some other things all on its own
wftda v2.1 ---> just passed; based on v2.0 but with
just enough minor changes to get everyone behind it.
Does not incorporate any 'lessons' from DD'07 or ECE '07.
Gotham '07 -- will bout under wftda v2.1, with minimal local customizations TBD. Maybe none. Maybe a handful.
