I don't see the option when I go to another users page. Is it because I have to make more posts or something?
There may be a post requirement, not sure. Go to your your user name on top right (profile page), click on it and a drop down menu will show up. On the right side there is the conversation entry, that is the pm. If there is a post requirement you might not see it or it may not work. Anyway that is where it is located.
I got it. When I click an avatar it shows - start a conversation. Probably just over looked it. Inbox now allows me to manually type in a user name to send messages. Thanks y'all.
