And I don't know how to send a private message.
Hello and welcome D
You can send an email in game (we use to say "send an izam") to anyone, just writing the homin name (even if the homin is not in your frined list), using this toolbar https://en.wiki.ryzom.com/wiki/User_Manual#Web_Applications
You can have a look on https://en.wiki.ryzom.com/wiki/Webapps_main#email
The wiki is better out of game. You can use the forum and several apps out of the game (using a browser such Chrome, Firefox...).
There's a User Manual here https://en.wiki.ryzom.com/wiki/User_Manual
and some tips here https://en.wiki.ryzom.com/wiki/Portal:Game/Gameplay
See you (My appartment is in Yrkanis - https://en.wiki.ryzom.com/wiki/Yrkanis_(city) )
