Stephen Agar is working on scanning and posting the full contents of his NAVB files, so a much more complete listing will be available in time (this is a large project and will take weeks to months). All I had to do was bug him to death and register my own variant website domain to force him to give up sleep and time with his family!
In the meantime, he needs some specific help and I have been assigned the task. Stephen's files (and what he has posted on variantbank.org, the un-updated version) pretty much only cover variants produced before 2001.
If you have variants which were produced since then, I need them. You can check the web site to see if they are listed at all. If not, I need them! Or if you're not sure, don't bother - just assume I need them.
Remember, as this is a variant bank (meant to be all ecompassing), we need not just the most recent version, but each major version along the way. So whether you're a designer, enthusiast, or just casual Diplomacy variant player, if you have electronic or paper copies of any variant which you think may not be in his files, contact me at diplomacyworld(at)yahoo.com. Without your help, we can't get this task completed!!!
