Thanks to Shermand for setting up an account and Kristian for negotiating it, you can now find all the tables I maintain with their latest versions at a site I can maintain myself (something other sites have not done a good job of, some carrying outdated versions and/or placing incorrect screenshots with the tables, etc.)
This site contains my new tables, current official table updates and authorized mod versions of tables I've worked on. This includes, as of this post, 17 different VPM tables and 21 table files (some tables have multiple versions for such things as a backbox or non-backbox version). All have viewable previews.
These are only tables that I actively maintain. Tables I've contributed to but let someone else maintain are not included.
Any new tables will appear there with announcements generally given at VPFF (The Visual Pinball Free Forums) message forums: http://www.vpfreeforums.com/
