I enjoy seeing even a simple "gla" (good luck all!) or "gg" or "good game" in the chatbox while playing games. Or other congratulatory or complimentary messages. Even these simple messages help foster good will and makes games more fun. Why not take half a second to share good will with those you play with? Or more time if you're up for it! Plus, chatting among players can actually be a big part of some games!
