Off-game chat?

[Alhanelem]

They'll never put something in the game for this purpose, however there are other resources you can use to communicate with others and catch up; ffxiah.com has a shout/yell tracker, which is probably more what you're interested in, and there's also the ffochat IRC chat server, which isn't server specific but it is "off game chat" that you can talk to people on.

Edit: reading again it sounds like you're already doing that stuff. Well I guess then there's not much I can say to help. I really don't see them adding a way to chat with players ingame from outside of it- I could see that being highly abusable by spam bots (not necessarily even RMT related- Making it possible to talk to the game outside of the game opens the door to the use of bots and scripts to annoy/abuse people to a greater extent than is already possible)
