Help I’m a Technophobe

When you are on the page of the discussion that you want to respond to, if you scroll down to the bottom of the page, there should be a box that you can type your reply in.

I hope this helps!

When you use the post comments button you reply will appear on the post for everyone to see 

This is how the forum is set up.  You can tag someone by putting @ before user name 

To reply to an individual without it appearing you need to send them a private message which you can do once you have 25 points 

To do this click in your 0tofikr pic then there is an envelope at top of screen click this to send pm 
Enter username of who you want to message without the @ in front 

Hope this helps
