New User, long time lurker!

Hi everyone! Just wanted to ask if anyone knew how to send messages to other users? Im looking to ask another user about a game their developing but I cant see where I can message them!

hello. if you click on someones profile picture or name you open a box where there is a button that says message

First off, welcome! and @Yamhead is correct. If you click on some ones name or avatar you will get a card like this and then you can message them.
