The Restart of the CD3WD Project
In November on 2021 friends of Alex Weir, Oliver Walker decided to restart the project with the help of other past friends of Alex, They ended up going with a new URL address due to the old one being taken over. This new website is Version 3.4 of the 2010 CD3WD site. With the help the help of past friends and people who have worked with Alex in the past the new CD3WD Project has gotten access to most of Alex Weirs work, approximately 250 Gb of data and documents to be released in 2022.
Please note the old websites are no longer up and running, Alex Weir died in 2014 the original creator of CD3WD, The site has been placed back online as the CD3WD Project as of late 2021 with the help of some of Alex Weir's past friends and can be found at http://www.cd3wdproject.org/
