Go to kmail, write a message, search for players, search for level 1, non-pvp, non-hardcore. Click search and then find the largest player ID #. That's probably a new player or close. You can /whois PlayerID# in chat and keep using higher numbers until you get player doesn't exist errors to find the newest players. Sending candy hearts with messages like "Join Clan" are cute little ways to get people to think about joining.
