I’m sorry that you had trouble to find a quicker way to send a private message. I’m not sure how many ways there are to do this in the new forum, but here’s the one I find the simplest:
1- Click on your avatar/name icon that you’ll find at the top-right of the page. In the the moderators2 profile this is the M in the red circle. This will show you a small pop up menu where you will find the messages icon in the green square below:
2- Click the messages icon to find your Inbox, Sent and archived messages on the left hand side, and also to compose a new message by clicking the blue New Message button highlighted in the green square below:
3- Once you’ve clicked the New Message button you will get a blank message window to compose your message. If you click on the Add a user text box highlighted in green below, start typing the username of the forum member you want to send the message to and you will get a list of forum usernames you can select as addressee. Just click the right one and it will select that username as addressee of your message.
4- After that, you can type the message title you wish in the next text box and the body of the message in the big box below and hit the Message button at the bottom when you’re ready to send your message.
I hope you find that useful, but do let us know if we can help with anything else.
