How can I add a private message button below the reply button on a post?

No-one can ever figure out how to private message on the forum I get complaints about it all the time, its kinda pointless to have it when people cant figure out how to use it.

clicking on the posters user name is not intuitive at all

the post needs to have a private message button somewhere clearly visible

EDIT: I just tried to figure out how to send a private message when using my phone and not a full laptop... in the mobile view clicking the username takes me to the list of their posts but provides zero way for me to send them a message?????

There is some sort of message bubble icon toward the bottom of the page that does nothing, giving the impression the messaging system is not working?????

I really love this forum you have spent so much time on, but I guess I should of spent more time using it on my phone other than just making sure it works...

at the bottom of each post needs to be 2 large buttons clearly visible , one saying post reply and the other saying send private message.

The super tiny icons at the top on mobile view are almost unusable and why would anyone need a stats button over a message button?

(also I had to start a new account since I can no longer log in by my username and the password reset never sent a pw to my registered address... no its not in spam)
