No such thing as clans in FFXI, closest thing is linkshells. You'll definitely get a linkshell before long.

Just a word to the wise, though: If you want to be an Elvaan in San d'Oria (as I am), don't go to the Asura server, Sandy's the bitch town there. On Alexander, my main server, it's pretty much an even match between San d'Oria and Windurst for 1st place every week. Dunno about other servers, ask around.

If you want a world pass for Alexander, let me know.
