Hey, I'm writing an article about IM and Jabber for Catapulse.com (they are a startup founded by the guys who created Rational Rose). In Jabber, if you send me a message and I'm not online, it's there when I get back online. Does anyone know if ICQ (or AIM, Yahoo or MSN) does the same thing? thanks, Mark Mark Wilcox mark at mjwilcox.com Got LDAP?
