Hi,
I meant to post this here a long time ago, but I never got around to it.
Before Wiktionary existed, I had made a website called "Languages in Languages" where people could enter the names of all languages in all other languages. It is far from complete, but I'm pretty sure that you can find stuff there that isn't already in Wiktionary. By now I'm pretty fed up with this site, and Wiktionary is way better anyway, so I'm asking you to go through the data and integrate it all into Wiktionary.

Please notice, however, that this URL only works when my computer is online (and I'm in England, so if you're in the US you'd have to try it early in the day).
If you want the entire data on one page, you can have it here:
WARNING: 2.4 MB FILE ! http://timwi.dyndns.org:8989/cgi-bin/a.cgi?r=l WARNING: 2.4 MB FILE !
Once you are sure that you have taken all the information into Wiktionary, let me know, so I can finally take this thing down :)
Greetings, Timwi
