Can't post a reply to any forum topic.

@elained I'm sorry you're having this difficulty in replying to a discussion topic. We always want to hear what you have to say! It might be a little bit different depending on whether you're using a phone, tablet, laptop etc. but this is my suggestion. When you see the forum topic you want to reply to: first click on the heading so that the topic opens up. Then you should be able to read the original post and at the end of the post there should be a curved arrow pointing back to the left. If you click on this arrow, a rectangle box should appear waiting for you to type your reply. After you finish typing you scroll down just a little to find the button Post Reply and click it.
If there have been other comments already made on the original post, you will find this arrow under each comment, so you can reply to that particular comment in the same way.
An alternative is that you can also scroll to the very end of the original post and all the comments and then you will see a box saying Write a reply. You type here and then scroll a bit further and click Post reply. I hope this helps you. Let us know how you go. Best wishes, Wendy, Moderator.

it may be something as simple as logging in? You can pull up MacularDegeneration.net and read stuff, but to comment you must be logged onto the site with your user name and password. At least that is my understanding. Best, Richard-Advocate
