Beware, shameless Propaganda is on its way. It's about the Interwiki-Link-Checker (http://tools.wikimedia.de/~flacus/IWLC/start.php) by de:user:Flacus, a brilliant tool which has facilitated the generation of >100.000 Interlanguage-Links within the last six month.
There are still lots of articles in en:Wikipedia which have the same name as articles in other Wikipedias, but are *not* linked by an Inter-Wiki-Link (e.g. en-de: ~6300 articles, en-fr: ~6500 articles and en-es ~3100 articles, as of the dumps from February 2006).
This articles have been listed for many language combinations by de:user:SirJective. But not all articles with identical names are about the same subject, so human work is needed to decide whether an Interwiki-Link can be automatically inserted by a bot. In order to make this decision easy and comfortable, there is a brilliant tool called Interwiki-Link-Checker written by de:Benutzer:Flacus.
You might want to check the FAQ at http://de.wikipedia.org/wiki/Benutzer:Flacus/Wikipedia_Interwiki-Link-Checke... or just try it at http://tools.wikimedia.de/~flacus/IWLC/start.php Thanks for your time and (maybe even) help, I can just invite you to try the tool, it's fun and you're reading (and editing) quite a lot of stuff you wouldn't stumble upon otherwise.
If you do like the tool and want to spread the word, visit http://de.wikipedia.org/wiki/Benutzer:Flacus/Wikipedia_Interwiki-Link-Checke..., help and new ideas are welcome.
Cheers, de:Benutzer:Mdangers
