NomicBoard was set up on Sunday 9th of April, 2004. It is a generic phpBB forum in which people can run Nomics as sub-forums, although it is no different to any other such forum software.
NomicBoard does not have any particular ruleset. It is currently running FishPond, which has started with a variation of the Suber ruleset.
19/6/04: Updated to include address of new host (me) currently, the site will only be up while my PC's switched on, so no dead-of-night postings, unfortunately. (The PC switches itself off at 11:30 PM, usually, and then wakes up when I do)
