sudanglo:Obviously Miland the transition point between language project and living language is not hard and fast, But to set it at 1887 for Esperanto is far too early.

I'd be more inclined to place it around the appearance of PAG and the Plena Vortaro.

If such things exist for Interlingua - based on analysis of actual usage - then I withdraw my contempt.

Age, Ceiger, in the sense of time lapsed since the first publication is not in itself a useful criterion. After all Volapuk is older than Esperanto.

Show me links for Interlingua that don't require a password, Ceiger. Show me a calendar of International meetings. Show me downloadable books (the Bible, and Shakespeare would be a good start).

The links I showed you shouldn't have required a password though? Maybe it depends on whether you have a google account, in which case I can't say much.

As for the research you require of me, well, I might do it, but quite frankly I find it hard enough to find that sort of info for Esperanto since it doesn't matter to me.

And whether a language has international meets or translated works does not make it a language, obviously. Otherwise I'm sure that vulgar latin wasn't a language at all before people started translating into that .
