Sadly, suricat, this forum is a lot less active than it used to be with many members no longer or rarely posting. For instance Ensign Muf hasn't been on since August 2021. I have just seen that you posted in some other threads in the Science section but no-one else did. That's partially because of fewer visitors and partially because those who do tend to look at the Big Brother section.
I noticed that some months ago you asked about how to create a thread. To do that, go the the forum you want to make the thread such as "Science and Tech Shows" Towards the top right look for an reddish/orangish button with Post in it. Of the options "What would you like to post" select Topic. Takes you to a Create Topic screen. Once you've composed the topic Publish button at the end to complete it. The Title Image is generally not used here, if you want to know more about it have a look at:

There is a way of letting another member know that you've referred to them and that is to do a notification. Type @ (wait for a second for that to become @ then start typing their member name and wait for the possible names to select. When you seen their name click on it. There's no space between the @ and their name. Type a space after their name and continue with your text. If their settings are set to receive notifications they should then get notified. Of course, it they're not set then they won't get notified.
@suricat as you can see your name appears as a hyperlink
