Warspear Online is a multiplayer game, where players interact with other players, they make friends, chat, etc. What if you want to go on vacation, but don't want to be kicked from your guild? Simply write your status "On vacation, don't kick", and it's sure the others will see it. Or if you have birthday and want to let people know it, update your status "I have birthday today!"
So you can let others know what's up with you. In a simple way.
This function would be really useful, I have missed it for a long time, and hope devs will add it to the game someday.
Another idea is the mail. Do you want to say something to your friend but he/she is offline? Leave a message! They will get your message as soon as they get online again.
Hope you like it, feel free to comment on the ideas!
