Ah, I see. The page I clicked on (CBM blitz) didn't have any nations signed up at the time, in that case.

If you put up a general page for the open games I'd put that up as a point of reference, but would then specify particular games if players posted a notice in the thread. In general I expect there's less organising required for the sort of small game your server hosts, since it's essentially each player joining in a vacuum, without prior knowledge of the other players or their preferences.
