Private message "OFFLINE"

I noticed there is a "guild chat off" on game option
Can we do that with private message too?

There are days where i dont want to be bothered much, where i just wanna focus on
leveling or the game what not..
and my messages get flooded alot by guild members or friends..
I think it would be nice if there's "private chat msg" off too or
at least an "APPEAR OFFLINE" on the game..
with the private message tho.. if you guys do agree, id suggest that if people try to message you
it should show "players currently doesn't take private messages "
or "could not be sent to user" some sort of that.. so it doesnt seem like were purposely ignoring ..

Just a suggestion what do you guys think? im not sure if it already exist but ya

i think why not its like u dont want to accept gifts, thers option for that so can be for not accepting pms at moment too.

should be mail service in game for offliners.
