Ryzom's chat (conversation windows) offer great possibilities. Still it is necessary to know them...
The explanations on this page are about IG chat (in-game). You can also use a browser, and have access to the chat without being logged into the game via chat. Very useful for exchanging links on the web (copying / pasting is easier there), or in case of technical problems or decoration / reco (log in with the name of the person played and the password of the game)...
