Hope toi will not be hurted par this answer of mine: If ever he has any email accounts well then it is for sure to be private and only accessable par people who is close to him like family,close Friends and important contacts. So as fans Sorry for we cannot chat with him.
....well, we wouldn't want to disturb Lee Min Ho, right???.....he's a very busy person, and..we should reconsider his privacy in life....although we're solid fans of him...let's not go to the point that we should enter his personal life...but, if he would allow us, why not???....its' a one-time opportunity as a fan of him....
kitty_kath is correct.. and also min ho is now a very busy person and don't have any time to be chat with.. so the best thing toi can do now is to support him with all your best.. have a nice day!
