Yes, the chat welcome message is different for each language. I only recently found out this myself.

Etc. There are likely 150 different pages.
 * MediaWiki:Chat-welcome-message/ro
 * MediaWiki:Chat-welcome-message/pl
 * MediaWiki:Chat-welcome-message/de
 * MediaWiki:Chat-welcome-message/es

While I can certainly understand the need to show a welcome message in a user's native language, there is no "global" welcome message, so it's particularly frustrating due to the lack of rules/help links for people using a different interface language.

Incidentally, to join the chat using a different language, you can use [ Special:Chat?uselang=de] (replacing that with whichever language you want to check)
