Every person is different but I would rather spend the little time I have to write messages writing messages in game and in character. Additionally, I have a hard time finding a way to ICly ask "What does the send button for contacts do on the Manage Contacts page?" I also think it is a bad idea to expect anyone to leave the game to get a question answered. Not everything needs to be spelled out but what a button does should be spelled out in my opinion. That is what these wiki help pages are good for!
There's an OOC message type for that...
