On the main Board page, can you see where it says Hello Copycat2018? If you follow that line all the way to the right you will see the date and time and next to that you will see a little box that you can click on. Sometimes we can accidentally click on that and collapse the options that allow us to see unread posts and new replies to your posts so try clicking on it and see if that helps.
As an FYI there is another way to view the boards:
Are you able to find the board you normally post on? Based on your previous posts, it is the Bettering a Relationship Board and the link for that is here:
https://bpdfamily.com/message_board/index.php?board=6.0Once you get to the board, you will be able to see all of the posts that have been made. You currently have 2 posts on the first page and 2 on the second (I did not check beyond that).
You can find the posts you started by looking at the column that is titled "Started by". You will have to scroll down to find your previous posts.
Once you find your name, look to the left and you will see the titles of threads. Click on the title of the thread you wish to read/respond to and then use this guide:
