Graal on iOS has been around for 4 years, at least for Era. I'm sure there are some strong friendship forged in that long run. Some players have quitted but still want to stay in touch with their friends on Gaal. Some are deleting the Graal temporarily to prevent the temptation to play because exams may be close or for some other reasons. Of course, they would still want to chat with their friends but doing that on the Graal app itself would urge them to procrastinate by ending up basing/sparring/pking instead of just having a small talk.

I suggest that we have a Graal messenger app where we combine players from all Graal servers to be able to PM each other. I know that kik is a common one, but some people already have a kik account for their personal life and they might not want to use it to talk to Graalians. Although creating another email account is possible.. nobody would want to take the pain to create one just for kik right...?

Therefore, I recommend an app itself for the game. Of course, rules can be preserved such as not enabling photos to be sent and vulgarities to be censored.
