Communication or Info given too solo play

What I'd like to see come to the game for solo players is a a messaging system ( 2 types of systems to be exact)

So the first is a note system - survivors would have to run to each other and past notes to communicate with one another...... Now with this system survivors would not be able to just spell out whatever they want..... there would be select words and start of sentences that would strictly be DBD related ----------> (ex. a beginning of a sentence could be ..... "There's a" ..... a single word in the system could be.... "generator") so the player would select the part sentences and words to make a message and give it to the other player letting them know what they have planned so the players can coordinate a bit better.....

the other system that I would like to see in the game - a graffiti system where players would leave messages behind giving direction to players.... this item would be the "spray paint" can be used to write messages to players even in other realms.... the messaging system would be an effort to help bring the community more together in an effort to lower the toxicity and a way to help newer players since experienced solo players would be able to lay meassages down giving tips and the newer player would be able to read these...

The graffiti idea I got from Dark Souls and I believe that with DBD's own spin it can work in game.. I really hope that you will at least attempt to implement this idea to help the community and bump solo play up towards SWF a little....

                                                          Thank you for taking your time to read this!
