Now, more than 4 years later, Bitcointalk has still its outdated, dysfunctional PM structure, where it's really a challenge to keep track + sometimes search or quote, what my PM people wrote me only weeks ago, for members getting usually quite a few PM's every week.
Or like me because I've a recurring list sent via PM, adding updated to this list every time.
I always need to dig it up in my messy outbox / inbox to find the latest version.

Recently, I've tried to look into "labels" function to label all my PM's to get a better structure into it.
But guess what?
It's only possible to label incoming PM's, not outgoing PM's (containing ALL my repliy PM's)... 
Honestly, the inability to label outgoing PM's is making "labels" pretty useless because I'd still have to dig up my old replies in my messy outbox.

Is it not possible to label my outgoing PM's, too?
If it's not possible, this is making "labels" completely useless as I would still have to search all the remaining messages. 
I'm so tried of this sick, dysfunctional shit.
